However, my understanding (limited) is that they basically take the top and
bottom of the voltage out of the sine wave. If the voltage drops, the
amount
of power that can be taken is reduced. Our microwave power is directly
linked to the voltage the generator is producing, even when running from
the
inverted/batteries which produce a true sign wave of 230v/50Hz the power is
down about 10%.
