It is a half bridge circuit using icsg3525 as a pulse generator about 55khz. Use gate drive transformer to drive mosfet irf740 transformer use etd42 winding 30 turns think how many v per round take 220vac*1.414=311.08dc ;'half bridge circuit we will only charge half the power=311.08/2=155.54/30 cycles
= 5.18 volts per cycle We need a 12v output. but the circuit with feed The back is to control the power to be stable. Must be wrapped to give pressure before feeding. back is higher in this circuit we will wind a transformer to output 25v take 25/5.18=4.8 rounds We are actually thousand 5 times. As for what wire number to use, see the table below.
