[QUOTE="shorai, post: 1118979, member: 24498"] I'm almost positive that is from some form of electronic regulation on the output of the generator. An alternator does not produce this waveform. It looks more or less like what I got from my first battery to mains inverter design. There'l be a microprocessor switching some Mosfets to try to keep the signal close to a sine wave. And insufficient (or no) smoothing. I count 80-100 spikes per phase which would mean the regulator runs at 4-5KHz (you might be able to hear this). A 50Hz filter should do wonders, but you will need one capable of handling the voltage and currrent. Good to see that I'm ot the only one capable of producing such junk. Mine got scrrapped immediately. [/QUOTE]
