Hi.
Am trying to build a DC/DC boost based on push-pull topology , since i have no meaningful experience in designing SMPS am kind of lost in how to choice the adequate transformer from any catalogue or are at least what data a manufacture need to know to produce a custom one for me.
I have calculated that i need a 36 turn ratio but i can't find one with this turn ratio in any manufacture catalogue, please help.
Power 200VA , input 12V output 350V,
