ok sir adamkaktus..i already made my own version of that smps...but it's been undergoing the series of testing yet, to make it really ok..it is half bridge, offline with 220v input, using
k2611 mosfet..is this fet available in your place?....the output is 50v and i still have to modify the winding to make it dual +50v, -50v...because the transfo that i used was the original ATX power supply 500w transfo with EE35 number...and it was very surprising becoz the 12v became 50v (without center tap terminal)in my design..tnx
