UCD 25 watts to 1200 watts using 2 mosfets

[stewin]

to GOD be all the glory. my latest project based on this forum. i read notes on ir class d layout and there has been an improvement on noise issues . this is more silent than my previous designs .
works well but care has to be taken when soldering smd parts . some are too close to each other, maybe some day i will order a pre soldered board have fun all

Hello fellow DIY'er,

I would like to ask I have IRFP250n from Harris semicondutor.. what the value of gate resistor I'm going to use.. I will use it in my IRS900

Hi,

Use 33R Or 39R resistor (fsw=300~350KHz)
Use 47R for 200~250KHz fsw

You design a version in tht ? Or equivalent smd transistors ?
What needs to change for transistors irfp250n ?

Hello everyone .
I would realize irs1500d , but I saw that someone had problems with this project.
I know that the issue should be on the level shifter .
If I replace the input part with AUD600 of manojtm, the amp works?

hi all my ucd class d . i powered mids at +/-75vlts and subs at +/-85vlts outputs irfb4227 . i used two half bridge smps gdt, irfp 460

used the sub channel @ 2ohms( four 8ohms 18" subs) and it warmed after pushing it hard for two hours. the mid channel I used 4ohms .and all was well .
