Abstract
A bipolar inverter has power switches connected such that the inverter can be energized with a d-c voltage of either polarity, or by an a-c voltage. Each power switch of the bipolar arrangement can include inverse-parallel connected thyristors, an individual triac, or a diode bridge with a thyristor connected across the bridge. A commutation circuit for a bipolar inverter is described. A single power switch also has utility as a power transfer component in addition to its use with an additional power switch in one leg of a bipolar inverter. Different circuit implementations for the bipolar inverter are described, including use with an induction generator, a heterodyne frequency converter, and a power regeneration system.
