Of course, if we were to put a transformer in front of the diodes, we could make it weigh a whole lot more and result in the same current waveform. I agree that it'll probably just clip off the sine wave peaks on the power line. I've seen some mention of CE rules on harmonic content, but these seem to be for devices that draw less than 16 amps. Are there other rules? Are there any US rules on line harmonic content? Thanks! Harold On Sat, 19 Sep 1998 17:48:19 +1000 "Paul B.
