![]() My design goal is to get 2X35V out of this SMPS this is why the core was rewound to 73 pri and 2X23 secondary. There is something i forgot to mention initially the EI-33 was taken out of a pc psu it worked with 220V giving 12V ac and 2 X100W bulbs in series but the waveform was not symmetric on the scope. Is this correct? Well Dr Pepper you're right and i did blow up some mosfets and most probably there is some more to come but i want to proceed step by step. As for currents I don't have a current probe but i can place a 0.22 ohm between the low side mosfet source and ground and show how the waveform looks like. Though this could be done with a flyback i still want to continue the half bridge way. As for the power I am not expecting more than 150W from the SMPS since the Max power for the EI-33 is around 175W from what i have seen from datasheets. Hi E-design and Dr Pepper thanks for replying.
