Hi
1) why not use one core w/ bifilar windings?
2) use snubbers on primary switches and more importantly the secondary rectifiers!
3) add common mode chokes on primary for sure and secondary for audio applications.
4) consider other designs for the IRxxxx housekeeping DC supply (see attached from my web search)
5) the more rectifiers you include make sec. grounding isolation better but they also add a lot of HF hash / noise overall.
6) for audio consider using feedback and / or other regulation schemes.

Hi !
Thanks for advice !

You mean to solder C5,C11 , HL1 , HL2 from your circuit in series whit gate on mosfet and R3,R4 ?
I think to use EMI filter on primary .

core whit bifilar windings i will change it .... I have this one , but don`t know how much turn to make ....

I use FR302 two at paralell because they are only 3 A . And i have a lot of them .

For output snubers 1n2/400V and 100R/2W ?

In some circuit output core is before rectifiers . Is this a better solution ?

For test it will be without feedback .

no main transformer , why use 2 ( a custom design yes)?
better to use more secondary windings than rectifiers. hint > use 4 windings instead

consider a small control PCB along with a point to point bread-board on vector / Vero board.
notice the main transformer provides power for the control after the start up sequence.

point me to the main Transformer information, maybe if you want, we could modify it.
are u sure they test it OK?

yes , it works .
Video

I want to turn on in original variant and when all is OK then modify .

Transformer for IR2153 is 2x7 volt in series . It gives about 18 volts .
Other two transfoermer are from ATX power supply . Whit out any changes .
