Abstract
A bipolar inverter circuit comprises power switches for providing alternating energy to the load notwithstanding the polarity of the energizing voltage. Each leg of the bipolar inverter or power conversion circuit includes a pair of power switches, each having a diode bridge with a thyristor coupled across the normal bridge output terminals to complete a path for current flow through the power switch when the thyristor is gated on. Each leg also has a complementary commutating circuit for turning off one of the thyristors whenever the other is gated on.
