Hi,

Yawn ....... Its the usual I've built the best thing since
bread, I wan't to brag about, slag off everything else,
but can't give details due to patents, blah-de-blah.

It will never see the light of day, they never do.

rgds, sreten.
 
To make this more fun we should start guessing what it is

I know - revolutionary (below) 😛

Hi,
Stay tuned , coming soon the revolution in an analog amplifier .
Some fundamental differences with the existing amplifiers today.
------------------
No simulator :

Totally independent from the psu . ( Dc power , from + / - 30V to 400V ) (in agreement only to power devices).

Dissipation independent of the rail voltage.(@ idle as bias)
Power dissipation ( from the input stage to the gate of the mosfet ) = 500mW .
BW Power (input to gate mosfet ) = 150Mhz .
Power BW ( @ output) = 10Mhz
Output Offset = 300uV ( under any circumstances )
SN / R = not measurable .
THD + N = not measurable in the range of 30W output.
total efficiency = 72 % @ 4R
Balanced input 2x600R
-------------------------------------
I did not start my life on the class AB , I have designed 3-4 amps , one is the HB- 300 . I applied others knowledge without a doubt.
For some time I had in mind to eliminate the classic circuit used in amplifiers , I see it as a "ball and chain" , unnecessary absorption , which increases when we want to get speed (for transients audio).
a lot of bjt , with the problems that we know. (I am referring to amps full)
None of this , we got an amp that seems designed by transients. 🙂

...."You can for change"

Regards

As this amplifier are designed by transients it explains why there are not measurable SN/R or THD+N 😱
 
hi,
Instead of showing interest, curiosity and other normal behaviors, you're having fun with my item. for me, nothing changes.
The version I will make myself available for amateurs, use the Lundahl transformer.
to be understood free assembly, excluding commercial.
I understand how hard it is to accept, especially for some who have built their life on the class AB.
I have respect for all those who work like me, 15 hours a day.
Not tolerate the incapable, whether those that do not have a scheme under the eyes, are not able to develop a new circuit. then modify and copy, copy and modify, what we have today?
With some of my articles, many things have changed, and you hate me?

wait the module, then diagram,instead of cip..cip..coccodè 🙂
 
...know well the Human brain ......

THAT's a fantastic achievement ! Congratulations.

This surely puts you far ahead of most mortal humans. This should blow everyone's mind. So far we've been hearing many scientists saying that the more they find out about the brain , they realise that they know very much less than they had assumed !

This should also mean that we would now fully understand things like 'the soul' , telepathy , teleportation and the myriad other topics connected with life in multiple dimensions and their inter-connectivity.

Or are you only talking about designing amplifiers ? 😉

Just kidding.😀

But yes , you have kindled a lot of excitement by starting this thread. You'd better deliver soon ! Otherwise I guess you will be converted into minced meat rather fast ! 😀
 
I started with the idea of ​​sharing the circuit ...

but you haven't

.... why this chaos?

facts are missing


it's been said many times that there may not be much new to find in solid state design
so if you really have found someting it ought to have interest

but not knowing everything that have been done out there could mean you may have to realise it have been done before

Now I stop when I'm ready, public modules, scheme and measure.

AP2. Patent applications in EU and US are published so that interested parties can object, debate, add to , and subtract from them. You may be able to release the application number if your legal counsel agrees. This diyAudio Forum will be a new avenue to challenge or critique it in a positive manner. But this collective feedback may need to be disclosed to the patent examiners.

By example, I visited www.uspto.gov and searched the patent application database using the term "audio power amplifier" in the Title. I got 26 hits. I'll sift through them later. One can similarly querry the granted patent database. A lot of new tech may be hashed in diyAudio Forum.
 
Interested in your new design. Someone who is in production stage of actual units, has applied for patents on their design, obviously has not designed a paper amp. Probably you have researched enough existing patents/designs to know if it is radically new or not.
I would have to take some issues with stating S/N not ''being measurable'' etc, or at least reserve a comment on that for a time if/when there is test measurement data released.
''Perfect'' linearity, phase and zero damping wouldn't necessarily result in great sounding amps... but that is a whole other topic.

One application is entitled Class AB-D audio power amplifier. No implication it can be is related to AP2 power amp. Just general info. I could not view the images; my compute's limitation.
 
Thanks to Antoinel for explanations , interest about my work and support thread.

Thanks also to others who show interest in research , without thinking about the problems of the business.

In the meantime I found out that the examination of the circuit has complications and can be accepted only in the completeness of the amplifier to be patented.

Basically I wanted to eliminate the cross- current modulation , and then is formed by two identical channels pure class type A.
now, if I close the entrance with simple transformer input (not as a driver mosfet ), the concept could be the evolution of the F6 Nelson Pass. ( also in this case , is a little more complex becouse i use multiple local fb, and two servo operated by a differential,etc.. considering keeping everything clean for 150Mhz power BW.

There is no doubt that an amplifier with this architecture , it is like an engine that flies to 20,000 rpm .
To this we must add something else to increase the efficiency 🙂

The project without transformer input is complex ( this right is already in production ) . ( we filed the patent for this ) .
Both version has the input is not referenced to gnd , and does not refer to a common point.
Each side is free to modulate the current without ballast .
excellent that allows the use of N channel FET . (without phase rotation in the gate of the mosfet)
Both play in multiple local FB + a NFB very low level .

Maybe you feel strange, but this work lasted seven months (between a job and the other),was not motivated as start, by business, but of course can have.

as promised, a version suitable for amateurs, will be freely available, I can offer only the PCB (4 layers). the commercial version uses 8 layers.
I honestly do not think I have done something wrong towards this forum.

Regards
