DIY High Power Mosfet

darkm4n · 3rd September 2004, 08:22 AM

Someone know a high power mosfet amplifier design ??
I'am aiming at over 400 W 8 Ohm RMS per channel ..
Can anyone help me with a schematic ?

I believe Randy Slone has a 550w @4 ohms MOSFET based amp, its Class B BTW.

Hi,

check this site. They sell an excellent 180W-classD module already and will offer a similar, but 400W module in a few weeks for a very(!) fair price.

Hi

Check out Randy Slone's site.

In the moment I'm building up this OPTIMOS-Amp.

You can ask Randy for the improved schematic.

I am not a fan of class D BUT if you choose that route Tripath makes a class T evaluation boards. Just add a power supply and a chassis and you have a new born amp

Darkm4n: Salut! What type of IRFP's do you have in your garage?

Best regards

Hi ,

I have a bountch of IRFP in my garange .. there is no problem in getting them .. anyway they are cheap mosfet's .. that i use in RF power amplifiers ..
Maybe a schematic will help .. ?

Thanks !
