HI
I use this schematic for a 700 watt power supply.output voltage is 36v and current is 20amps.the core is etd44/freq is 50KHZ/primary is 30 turns litz(6*0.55)/secondary is 9 turns litz(22*0.55)
circuit worked but after 1 minute secondary winding become very very hot and i can't use power supply more than 2 minutes.
what is the problem and cause of this hot secondary winding?
