700watt smps based on acca's circuit..

here is the transformer.. erl35..

here is a pcb from acca

change core at bdt? and what core can i use? i have ee16 eel16 ee19 gaped acca please chek you email... 300 watt load with mje13007..

i winded 8 turns but the problem still exist... i used 5watt 22ohm resistor but it's too hot again.... this is my secondary... is there any problem at the sec?

acca i'm done with this.... it was the last smps i tried... i have an 1kva transformer core... so i will wind this transformer and i will have no problem.... this is the schematic i used

this is the way i think to do it.. is it ok?

here are some photos... smps is not finished yet...

here is the first storage inductor...;) i have to make another one... 120 turns at t37 yelow core...

i make this... i have a pair of 3.8 cm ring cores... how many turns should i make?? 1v turn??

i want to build this smps.. i need about 500 watt in order to power an audio amp.... instead of ee19 base driver transformer i want to use an uu10.5 ferite core because i have a lot of them... how many turns i have to make at uu10.5 core?

hi guys.... i have soem str41090 and i want to make an smps with one of them.. or more of them in parallel.... has anyone work with this ic? i can find some schematics at google but i dont know the how many watts it can outpout... i dont know aboy the transformer winding to.... can anyone help me?

hi guys... i want to build a power amplifier with irs2092(discreat)... can you help me find a good circuit with pcb? i have a +- 70 vdc power supply.....

hi guys.. it's my first post here.. i want to build an smps to power a 2 chanel class d amp... i have an er54 ungaped core and i want to use it... i'm thinking of building this circuit http://www.classdaudio.tk/index.php?page=hb_prot2 is this a good working circuit? i saw at the cct that the...
