ABSTRACT:
A power conversion unit for supplying electrical power to a load from a polyphase a.c. source includes a controlled rectifier bridge connected between the source and the load. Control of the rectifiers is provided through the generation of a firing wave signal for each phase of the source which wave signals are phase displaced with respect to the phase-to-phase source voltages by a prescribed amount. Reference signals proportional to the desired output of the bridge and steering signals defining prescribed relationships between the firing wave signals are combined with the wave signals to generate signals utilized to control the conduction of the bridge rectifiers.
