The load is 4 x 750W (at 220V..) Lamp in parallel.
The temp of mos is 41°C during the test with 800W load (788W)
The voltage on output is 100V with no load (+/- 50V) And 86V with 9Amps load..
The transformer is ETD49, wound with 0.4 mm X 5 wire. Primary have 22 Turns and secondary 2 X 7 turns.
Frequency is 77Khz
The gates of mosfet is drive directly by the ir2153 with 10Ω resistor and 1n4148 diode
I have make some changes and i make a new pcb soon.. Protection card not tested yet !
I will winding a new transformer soon with 0.1mm Wires
