Anyway, if the voltage regulation is critical , an
electronic regulator would work far better.

Would it be better to regulate the peak, average or RMS voltage if the
load draws non-sinusoidal current?

I became concerned with the peak after a poorly regulated generator
burned out the transient voltage suppressors in an outlet strip, in a
cloud of purple smoke.
