A ringing problem is usually a layout problem due to too much parasitistic inductance, and judging by the pictures, your layouts seem always quite clumsy with long wires and the like. Anyway, you should rather start by laying out your room and your workbench properly first, and employing fuses to prevent things from melting down!!
Note that I'm very prone to destroying components due to distractions, yet I have developed a class-D prototype operating directly from rectified mains (340V) and producng +/150V and +/-30A output while blowing only a pair of IGBTs, an IR2112, a 74HC86, a LM393 and a pair of small transistors in the process so far. So you must be doing things really wrong in order to experience so much trouble, even in very forgiving low voltage circuits.

No point continuing the way you are no! Maybe you should learn to experiment in a smarter/cheaper way. It's not as fun but start with a simulator before you go spending 100$ on a PCB for a downloaded and unproven circuit, or you can really expect it to cost you a fortune. Then you can take it to a breadboard.... 20$.... but then I guess you can't laugh at people for their ratty looking DIY projects (that still work) 🙂
You shouldn't have a screwdriver near it when it's powered either. Two good lessons for the price of one, not too bad.

Eva I'm sure the difference is that you work smarter, research things.. and maybe know more already. Obviously you do your homework though.
Something actually distracts you while working that kind of stuff?!?...... cellphone? 😀

Tekko said:This time it was due to shorting something out with a screwdriver, it killed atleast the fets so i replaced them with IRFP250N, they got hot instantly, even the cables between trafo and rect melted.
But this have costed alot of money this far, and theres just no point continuing.
I feel what you feel Tekko

Well, That's the life of a genuine workaholic hobbyist😀 . NO pain!! No gain!!


The TL494 alone is enuf to drive my old computer speakers
, no bass allowed tho.
I dunno why i even started on this project, when i have no knowlege at all.

I would have hoped..... it would have been to gain some? Research!!!! Did I say research??
Class D amps are an excellent learning grounds because it's such a marriage of the different avenues of electronics, and partly because of that you can't expect to just plug something in and have it go.
Hell, I'd make it a point to get it going again with those very same mosfets that cooked it, if it takes you six months.
Sometimes when you hit a little wall it's good to take a little break from it though, and it will eat at you enough to want to get back to it.... give it a few weeks 🙂
If you're not at all interested in learning though, buy a proven module, I guess.

When 200 euros is spent already ?
I even trashed a B&O ICEPower module for this project, gutted it of fets, the op coil and some caps.
I consider myself too dumb to continue.
I have killed the TL494 on the board too now to be able to call it total loss.
Im not willing to spend any more money on this project.

Could have had a couple UCD180's for that price ... if all you wanted was sound...
Obviously since you trashed an amp towards the project there must have been another motive to it than that.
The amp would have been the last thing I'd have trashed.
My homebrew UCD ... I trashed 2 broken but repairable computer monitors... got some good mosfets out of those, scavemged alot of small signal low noise transistors from my old pioneer junk amplifier that was smoked, scrapped 2 computer SMPS that were still good.... but they're a dime a dozen so who cares. They're so cheaply built anyway that the only thing of value in em was some plates of aluminum.
Another 20$ on small signal transistors at radio shack, and later on I went through about a dozen mosfets, since I was "tuning" the gate signals without the use of a scope, using my finger as a temp sensor and my simulator as a best guess generator.
Those were free samples (Thanks Fairchild).
Later on when I wanted to make it more permanent (10$ breadboard up till now) I trashed a >400$ robot to re-use the perf board it had.
Total cost, next to nothing. Build time.... well over a year, learnt a few things.
Hmmmmmmmmmm ..... boy am I stupid! You're right you know, it was crazy of you to even try.... may I have your scope since you won't be using it? 😀

Only one thing Tekko, continue. People like classd4sure that only whant to prone UCD and never built something better or try something else should not judge you! I have spend over 100 000$ to design and learn on class d, never use simulation because they always be far from reality, but I have make lot of calcul and ''simulation'' on paper from experience..
Your on good way, just listen a bit more on what people told you and judge the pertinence of this. Their not a lot of ''real hardware'' thread, this one is a good one. Unfortunately, most of the thread talk about modifiying an existing module, that's mean that's performance did not match what's people expected!!!
Do your project to sound as you wish and you will be the most satisfied of us!
Unfortunately, I can not give to much secret here, because I manufacture already product and I have a lot of OEM design for big customer, that for sure they wont I give secret of them design..
At least, got to thread http://www.diyaudio.com/forums/showthread.php?s=&threadid=77659 for fews idea!

fredos, im out of parts once again and around 200 euros is spent.
I have given up on this.
Or should i give it one last shot but with IR2111 instead ?

Sorry to have hit you like this classd4sure.....Not good email you just send me! I just talk about the fact that in all your post you talk only about the UCD, it seem that your never try something else! UCD seem to have lot of fan's for their sound and avaibility, but unfortunately, I see too a lot of people with syncronisation probleme (major issue for pro audio when lot of channel is required) thermal issue at hight power long term demand, and variation in output power that depend of power supply. And one major probleme read a lot of time just in these forum about beating when use with switching power supply.
So for personnal use in limited configuration, it seem really good. I never got a chance to listen to these module, and maybe never try it because of the free running topologie. Just a hint to UCD company, add a sync input to sync your module to a higger clock frequency for pro audio use! I have test a lot of competitor class d module, and so fare I only give respect to B&O, except for over rated power.
Sorry again to have hurt you classd4sure, that just my opinion, and I have try to give a push to tekko to continue is work, because their not a lot of ''real'' hardware guy on this forum! Thanks to Eva for lot of practical technical advise too!
So please try to explore more avenue for class d amplifier than UCD! Evolution of class d is not finished, but just begin!

Hi Fredos,
Yes its fact that pro-audio gear is completely different from home audio gear...in case of UCD its one of the most popular Class-D module because of its fundamental simplicity, superb sonic performance and ease of use as ready to use module as compared to other solutions....
Whereas in case of Forced Clock based Class-D amps, they require some what more engineering to get the stuff working in right direction and also Synchronisation is achieved very well in these clock based modules...You can sync as many amps you like..but thats cannot be done with free running class-D amps..
Here on this Forum thinking of people is usually confined to some reference design which has made good points, therefore they cannot let themselves to think "Beyond" the so-called boundaries as the expansion of Class-D amplifier design & engineering has much greater & vast horizon...no matter what rules out there is always a new frontier waiting for you! Thats the Challenge for those who are innovative..and possess a skill set in this art...
Pro-Audio has its own Set of Rules..
1. The Show must go ON...Thats the reliability factor which counts most.
2. Environment Adapability and user accessability of pro-audio gear is most important.
Dont get dissapointed from this people...Lets Cheer!
Hi Classd4sure,
Why donot you let Tekko to learn from its mistakes and gain some experience in that field......You should encourage him, please donot discourage him...
If you are a Fan of UCD or you love it..it doesnot matter but thats not same for others like Tekko who want to build their own and thats the main reason for what we are here on this forum Just to DIY!...."DO IT YOURSELF"

Hi,
Fred, yes I do post alot on the topic of UCD. You've displayed some ignorance in allowing yourself the conclusion that that's my only avenue of either exploration or interest.
Same to you Workhorse, you can't be in love with a circuit, but you can certainly admire it. Thus far the only one worthy of my admiration is UCD. If you know of any others I should know about, do let me know.
Personally at this time I've no interest in clocked designs, because in my opinion, there's just no need for the added complication they bring in order to do them right, when they offer no significant advantages.
That said, neither the UCD, your misconceptions about it, or Pro-Audio is the topic of concern... and Fred, your attempts at using any of that to validate your previous comments fall short.
As far as valide arguments go, Workhorse brought up one that I intend to elaborate on. "DO IT YOURSELF".
First of all, Kanwar, I truly appreciate the nature of, and thank you for your comments to me. If you ever seriously believe I'm discouraging anyone to DIY, please do let me know, and I will check myself immediatly, but I think I'll be the _last person_ to ever actually discourage it.
There are things however, which I will readily discourage. Here I'll present to you a few of them.
Fred, you're in _total error_ to think there's a lack of "hardware" guys around here. Try posting something "worthy of their time" and they'll be all over it faster than you can imagine.
What there is, however, is a serious lack of the kinds of researched and informed questions around here that will prompt them of their attention. This is exactly what Tekko here is largely guilty of in my opinion. Now I'll follow that with what I think you're guilty of.
You have here, a person that obviously puts ZERO!!! time or effort into the research of his problems, or the nature of any of his questions. This is portrayed by such posts as "do these circled parts have anything to do with..?" an uncountable # of repeated "which core" posts and many many more.
If he does get a reply from you, Eva, or anyone he should probably be paying some level of attention to, should they be so kind as to offer their time and expertise (which by the way will take them more time than he ever spent researching it) he then readily ignores it, because he doesn't begin to understand, and/or is simply too lazy to try. Then when his plug and pray style of "design" or "troubleshooting" doesn't help, he repeats the same questions over and over again while ignoring the same advice over and over again.
You, Fred, are guilty of coddling him to the extent, that you actually have posts of the following nature:
"Tekko, listen to what Daddy has said. I did promise you a candy but you failed to clean your room as I've been asking for two weeks now, when you clean your room like Daddy asked, Daddy will give you some candy".
That Sir, is what I see when I read what goes on here, and I'm fairly disgusted by it. The other hardware guys have the sensability to not reward such lazyness, why don't you!?!? By coddling him in this way you both impede and nullify any possible lessons he may have had the oppertunity to have learnt!
So it isn't at all my intention to discourage DO IT YOURSELF, it is my intention to discourage DO IT FOR ME. Especially when said person obviously doesn't know of a search engine, ignores the advice over and over aaaaand over, and the very second that plug and pray fails to work or Daddy doesn't reply fast enough "I quit, please delete this thread... I really quit this time... this time I quit for sure". This is simply vulgar behavior on an otherwise excellent DO IT YOURSELF forum which I find you to be doing nothing but encouraging.
Instead of giving him answer after ignored answer, rather point him to a damned app note or a search engine, or just give him a few keywords to work the rest out with for himself until he can at least ask an informed question, and is forced to adopt some level of competency troubleshooting. When that's happened and he actually makes some effort, he will treasure every single piece of advice given to him instead of totally ignoring it. That'll be the most valuable lesson you can possibly teach him at this time in my view, because he hasn't learnt a thing yet and if you continue this way he never will either. How's that grab ya.
As far as simulators go, I think they remain an excellent tool, even beyond DIY, allowing one to try variation after variation without having to spend a single dime. As someone who's admittedly spent over $100K re-inventing the wheel you really ought to have learnt this by now! Yes they are not ideal, that itself is simply the first lesson which they have to teach, but it by no means precludes their use.
Why on earth would you not want to see the ideal response of a downloaded circuit before spending 100 euro on a downloaded PCB for it... I think that's a good lesson, not everyone has the kind of financial backing which you seem to, and there's simply no need for learning via DIY to be done in such a wasteful way. How your run your business is your business.
Maybe I'm blunt and of the unpopular opinion, maybe you lose respect of me for it, if you had any to begin with, I don't really care. That's my view, I know I'm right. For all the answers you've given him, you've yet to actually help him at all.
Stop the coddling would ya.
All that said, I fail to see how that is discouraging to DIY in any way shape or form. Rather it's encouragment to really learn how to first DIY and in a more efficient sensible way, which you've failed to do.
Now I've said my piece in response to you and workhorse... I tried getting these points across in a less insulting way to Tekko, they're hard lessons, and if it cost him 200 euro to MAYBE learn that, they'll be his best spent 200 euro ever! You as his enablers will obviously defend the behavior, and so I found myself left with no alternative but to spell it right out for you, insulting or offensive as it may seem, it really was not at all with that intention... I spared that aspect of it for email
😀

If that were true you'd be asking far better questions and appreciating the advice you're handed much more!!
Obiously what you think is alot of research ... is not. I can imagine the kind of time required for it, that's why I can say this to you.
If no answers describe the problem you're asking the wrong questions. Use the simulator to check your theories and that which you read. It will be much cheaper. Scavenge your parts from the cheap broken junk that you find everywhere at no cost, not 200$ amp modules... are you getting this?
I blocked you on MSN because you asked to see my work which I spent next to nothing on, still works, was the cumulation of over four years research and almost 2 years hard effort simulating and experimenting, without a scope to tune with. _You can't imagine the time_ indeed... and you were _punk_ enough to laugh at it?
Still I do you this service telling you what no one else seems to want to. If that scares you off the forum so be it, a DIYer you'll never be. No coddling here my friend.

Same to you Workhorse, you can't be in love with a circuit, but you can certainly admire it. Thus far the only one worthy of my admiration is UCD. If you know of any others I should know about, do let me know.
You think of yourself as you are the only who admire the UCD on this forum by posting alot of threads/posts on it....
Than what about others who also admire its superb features which include me as well.....
Personally at this time I've no interest in clocked designs, because in my opinion, there's just no need for the added complication they bring in order to do them right, when they offer no significant advantages.
If you have no interest in clocked designs then its your own personal matter and thought not of all other members preferably mine and Fredos...
Synchronising is one of the most important and significant feature offered by clocked designs which is not available in self oscillating type class-d amps....
By the way do you really know what are the real benefits of synchronisation You do very well know it! don't you..
That said, neither the UCD, your misconceptions about it, or Pro-Audio is the topic of concern... and Fred, your attempts at using any of that to validate your previous comments fall short.
As far as valide arguments go, Workhorse brought up one that I intend to elaborate on. "DO IT YOURSELF".
It seems to me that you don't even know what is the basic difference in design of a pro-audio gear and between a home audio gear...
Could you solve my problem of eliminating Beat fequency Oscillations occuring and giving rise to awful sounds when a bunch of Self oscillating Class-D modules are powered from same signal source as well as same power supply source and that too without synchronising them which isnot possible, if yes then please let me know so that i could update my knowlegde!
If he does get a reply from you, Eva, or anyone he should probably be paying some level of attention to, should they be so kind as to offer their time and expertise (which by the way will take them more time than he ever spent researching it) he then readily ignores it, because he doesn't begin to understand, and/or is simply too lazy to try.

Absoutely Incorrect Mr.Class-D 4 sure....We arent coddling him and nor we are validating the inappropriate questions here...if Tekko isnot able to do the research or enlighten some of his design mistakes then it doesnot mean that we should simply say that
" You are wasting our time ,Hence we would not give any advice to you for solving your problems"
but the fact is that you are simply ruining the DIY spirit by making him aware that he is not capable of doing anything therefore letting him to purchase some readymade module amp and say goodbye to this forum and he may sat on his chair listening to that module in which he has made no contribution except from paying $$$ to get it and must feel satisfied by simply listening to his no way creation....
So it isn't at all my intention to discourage DO IT YOURSELF, it is my intention to discourage DO IT FOR ME. Especially when said person obviously doesn't know of a search engine, ignores the advice over and over aaaaand over, and the very second that plug and pray fails to work or Daddy doesn't reply fast enough "I quit, please delete this thread...

I think Tekko already given you that answer in previous post
Maybe I'm blunt and of the unpopular opinion, maybe you lose respect of me for it, if you had any to begin with, I don't really care. That's my view, I know I'm right. For all the answers you've given him, you've yet to actually help him at all.
I dont take the things personally as you do take them and thats the biggest thing of difference between you and me! because I take them professionally not personally....
Stop the coddling would ya.
Why donot you stop discouraging him ! and letting him do what ever he wants.....He doesnot says "Do it for me" because he doesnot know how to do it.....😀 😀 😀 😀

Same to you Workhorse, you can't be in love with a circuit, but you can certainly admire it. Thus far the only one worthy of my admiration is UCD. If you know of any others I should know about, do let me know.
You think of yourself as you are the only who admire the UCD on this forum by posting alot of threads/posts on it....
Than what about others who also admire its superb features which include me as well.....
Personally at this time I've no interest in clocked designs, because in my opinion, there's just no need for the added complication they bring in order to do them right, when they offer no significant advantages.
If you have no interest in clocked designs then its your own personal matter and thought not of all other members preferably mine and Fredos...
Synchronising is one of the most important and significant feature offered by clocked designs which is not available in self oscillating type class-d amps....
By the way do you really know what are the real benefits of synchronisation You do very well know it! don't you..
That said, neither the UCD, your misconceptions about it, or Pro-Audio is the topic of concern... and Fred, your attempts at using any of that to validate your previous comments fall short.
As far as valide arguments go, Workhorse brought up one that I intend to elaborate on. "DO IT YOURSELF".
It seems to me that you don't even know what is the basic difference in design of a pro-audio gear and between a home audio gear...
Could you solve my problem of eliminating Beat fequency Oscillations occuring and giving rise to awful sounds when a bunch of Self oscillating Class-D modules are powered from same signal source as well as same power supply source and that too without synchronising them which isnot possible, if yes then please let me know so that i could update my knowlegde!
If he does get a reply from you, Eva, or anyone he should probably be paying some level of attention to, should they be so kind as to offer their time and expertise (which by the way will take them more time than he ever spent researching it) he then readily ignores it, because he doesn't begin to understand, and/or is simply too lazy to try. Then when his plug and pray style of "design" or "troubleshooting" doesn't help, he repeats the same questions over and over again while ignoring the same advice over and over again.
You, Fred, are guilty of coddling him to the extent, that you actually have posts of the following nature:
"Tekko, listen to what Daddy has said. I did promise you a candy but you failed to clean your room as I've been asking for two weeks now, when you clean your room like Daddy asked, Daddy will give you some candy".
Absoutely Incorrect Mr.Class-D 4 sure....We arent coddling him and nor we are validating the inappropriate questions here...if Tekko isnot able to do the research or enlighten some of his design mistakes then it doesnot mean that we should simply say that
" You are wasting our time ,Hence we would not give any advice to you for solving your problems"
but the fact is that you are simply ruining the DIY spirit by making him aware that he is not capable of doing anything therefore letting him to purchase some readymade module amp and say goodbye to this forum and he may sat on his chair listening to that module in which he has made no contribution except from paying $$$ to get it and must feel satisfied by simply listening to his no way creation....
So it isn't at all my intention to discourage DO IT YOURSELF, it is my intention to discourage DO IT FOR ME. Especially when said person obviously doesn't know of a search engine, ignores the advice over and over aaaaand over, and the very second that plug and pray fails to work or Daddy doesn't reply fast enough "I quit, please delete this thread... I really quit this time... this time I quit for sure". This is simply vulgar behavior on an otherwise excellent DO IT YOURSELF forum which I find you to be doing nothing but encouraging.
I think Tekko already given you that answer in previous post
Maybe I'm blunt and of the unpopular opinion, maybe you lose respect of me for it, if you had any to begin with, I don't really care. That's my view, I know I'm right. For all the answers you've given him, you've yet to actually help him at all.
I dont take the things personally as you do take them and thats the biggest thing of difference between you and me! because I take them professionally not personally....
Stop the coddling would ya.
Why donot you stop discouraging him ! and letting him do what ever he wants.....He doesnot says "Do it for me" because he doesnot know how to do it.....😀 😀 😀 😀
regards to Class-d4sure for sure!

Wow lot of philosophy here! Sorry to hurt you classd4sure but happy to see that lot of people have realize that hardware is important!
Please continue to work all togheter to advance in class d design!
I will try to share the more I can!
