Just out of curiosity, can you share a bit more about waveform<br>
distortion?  Was just looking at schematics for a 12-pulse converter and<br>
different winding configurations<br>

does sudoroom have an isolation transformer?  it's something that plugs into a regular outlet and outputs the same voltage, but it's isolating.<br>
<br>
we have a couple of universal AC converter boxes which provide 240VAC when you plug them into 120VAC but they are "autotransformers" and they don't isolate.<br>
<br>
I want us to have an isolating transformer so that when people experiment with AC-powered devices, they are much less likely to suffer a lethal shock and die.<br>
<br>
note:  some voltage-regulator transformers are isolating, but since they distort the waveform in order to achieve the voltage stabilizing, they are not ideal for our purposes.<br>
<br>
thank you,<br>
