Default Hello - ChocoHolic

I am reading your posts about Class D amplifiers and am very interesting about them. I have made a few mid-power amplifiers class B and now i want to build by my self class D amplifier. The problem is that i do not have eny curcuits to do this because i want to build power amplifier (600-1000W). So i ask you for some schematics if you have or may write eny sites from which i can read aboute these curcuits. I will be very grateful if you help me.
best regards.

Hi World!

Up to now I do not have the full design. In fact I am doing this project for my own education and curiosity. It is about the passion of understanding and finding good solutions.
To build a working amp in your intended power range you will need not only need a schematic but also a PCB and good electronics knowledge. The available parts of my circuits I have already posted. And most of it is not tested so far. It is OK for me to disclose the design here, but I do not have the time to provide a bullet proof design documentation or to teach from scratch hundrets of people by mail.
Look, even if there will be working PCB in the end.. even then I doubt that it will be a bullet proof design, which could avoid or forgive mistakes when being copied without detail know how.

...somehow I am wondering...
I am posting:' hi ! This is my new idea....' and I am hoping for a fruitful technical discussion.
Unfortunately the posted responses can be simplified to:
'When can I rebuild this amp and how?'

That's a little bit frustrating.

1st ucan build a 50w~100w project, even a class-d chip
is great diffrent between class-ab and class-d,

after that u can build a 250~400w class-d amp, is a hard work,
half-bridge,not so easy,

and then goto the 800w, or 1000w full-bridge

<< a little bit frustrating.

hmm, maybe. its same for me, i made a little amp, but there is also not much fruitful feedback..
(see at: http://sodfa.de/ , "cheap-d" )
now i think about a little bit more power: 300v supply, 1,5kw / 8 ohm
also clocked, with ir2110 driver, but lm319 as comp.

Default Hello

Thanks for your advise Fumac. Until now I have allready done two low power amplifiers class D with integral design. Yes there is difference between 50W amp and 500W but i think that i have basic knowledge to do such powerful amp.
I am sorry ChocoHolik that i am disturbed you with my post. I just sow that you have good knowledge about amps and i supposed that you are making amp by taking the curcuit from some magazine or somewere. I apology for my wrong conversation.

alfsch thank you about suggest site ..but i do not know German

I will be greatfull if someone may offer me some curcuit about power amplifier 500W-600W
Have a nice day!

I managed to download it but the site is very very slow.
I can send you the file but you need at least a 5Mb mailbox.
