    Be interesting to see what happens from 90Vac to 304Vac.

    Agreed, I'd be interested in 110VAC range.

    As I said it does not do anything above 39 or so volts. So where is the problem?

    After the sine wave has reached the 38-39 volts the circuits is not powered any more from the power line.
