Hey guys, I'm working on a SM power supply circuit which has 220 vac /50 Hz input and the result should be 1000 V 0.3 A, The required transformer will be after the first rectifier circuit connected to a Half-bridge inverter circuit with operating frequency 20 KHz at 45% duty cycle, the input of the required transformer will be about 320 V in DC ( 220 vac after full-wave rectifier circuit ) and with output of 1500 V and 0.6 A. Note that the primary winding are 39 turns and the secondary winding is 321 turns. Please if you have any information about the required transformer tell me about it, thanks in advance.
