jyanof, can you make a quick description of how the circuit operates? From what I gather, the battery and a 47k resistor are always in series with 240(ish)VDC. Then when the mosfet is on, the battery is then in series with the 2 coils straight to 240... so a pulsing of the mosfet causes a drop in voltage at the negative terminal of the battery (from the 100v or so that the 47k was holding up, down to near 0) and the coils push the current. (I'm no power electronics engineer!)
