Or do you have schematic of GOOD smp 600-700W 2x50-60VDC. I need for amp D class (for subwoofers)

As I said before, this weekend open a thread and put complete doc for smps (IR21531D) as photo at page 2 (blue pcb). I think is good for you, very stable.

dear AP2

is the making of PCB difficult? is it possible to share the diagrame of the circuit?

thank you

Back this treat from death

I builded smps but i didnt have overcurent protect and everuthing blow up third time that i started

Its no meter... Now I wanna build SMPS 1KW with +-50V, IR2153, and ETD49 and IRFP460
I uploaded schematic and PCB and can enyone help me out with some questions!?

Unit with IRF730 is for IR2153 supply with zeners 15V (you can see that on board.. (can enyone see its good like that)

Board is small (real size is in PDF) and I found 1000uF 200V caps with 15mm diameter and 60mm high...

I have few questions:

1) Is my board good for this smps?
2) I can find in my country ETD49 core 3C90 and ETD49 core 3F3, which of these can I use, same question is for EE16 for curent sens?
3) Do I need air gap on central leg?
4) I dont know number of turns and wire ticknes for primary and secondary (I need +-50V)
5) Number of turns for EE16 current sens transformer and wire tickens?
