I think I understand it. Move the upper N to L2??

Yeah, now let's get his face butned off so he can't post from the burn unit
at the hospital.

At least he understands it Josepi...which is what I was looking for, an
objective opinion. You could have easily done the same thing. It's still
not too late. You will find that I do not hold any grudges. Many of my
closest friends come across as a little looney when I first met them... :)

 Might be fun to try and get one working using a 12V to 110V (or 220V?)
transformer. Can you program an AVR (or shhhudddder, a PIC) to get a
60Hz PWM sine wave out of an h-bridge? You measure the juice across a
current sense resistor using a diff amp. The current should be going
in and out 60 times a sec. The volts across the resistor should be
going positive and negative 60 times a sec. Its the average thats
going to be a little positve or negative that is used to adjust the
drive amplitude. Also need to make sure the generated sine wave
restarts at zero at the rising zero crossing of the line.

It's a simple circuit....  Hook it up.

Let us know how it goes.
