I set up this fullbridge and it worked, extract about 1500w at 4ohms with 2000w source, I am using 2 pairs of irfp260, the problem I have is the output set with about 900mv, does anyone know how to solve it? thanks

look attachment schematic

I cant see you have this in PCB,

add 10K pot like in schematic and try to have DC 0 - 10 mv

You have old design PCB with error, 10 K Pot for DCO is missing, you cant adjust to 0mv if you not add 10K Pot to ground look attachment.

After add you can adjust DCO to 0 mv look pictures

PFC inductor advice

 

[cdmonty]

hello good morning everyone, i assembled the d2k and it worked perfect.
I would like to assemble the discrete UCD but I don't know which of all the files is the one that works stably.
Can you help me?

 

[NMOS]

There are some updates

1. look schematic and PCB 3D

Important is Flattening and anti Hiss Update

I have add DC Protect Triac Crowbar


2. also i have make control Board with Limiter and PWM temperature Fan control

look PCB 3D Top and Bottom


Do you want make new PCB ? believe me its a nightmare

I did it during 2 months Covid-19 lockdown

I made several PCBs from other class D amplifiers, what is the problem with the PCBs of this particular amplifier ??
I use the old Sprint layout
