Hi all. Im experimenting with lawton circuit to for my Wfc. When i connected a bifilar coil before the Wfc the amp was reduced significantly. It was true that bifilar can reduce the amp. But i think that i can also use this circuit to pulsed a bifilar or multi bifilar to become a bendini charger. Im still experimenting and my bifilar get hot. I think this can be done. I think want to connected the Wfc and bifilar in series so i can use it for two purpose. One for the charger and for the Wfc. I will post my result later. Sorry for my broken english.
