Can i power this by mains 230VAC@50hz if i modify it? i would add much more turns and get some really beefy mosfets, maybe igbts, that would handle the rectified 320VDC.
one of them is inverting and the other one is non-inverting. in half bridge, one transistor MUST be turned off while the second one is turned on. you need to use this setup, otherwise it would short the circuit, melt the wires and maybe explode.
If there are 3 pins on your capacitor, two of them should look the same. Connect those together and connect as pin 1. the remaining pin should be the 2nd one. Hope it helps
