Abstract: A circuit for powering a two-phase AC induction motor. The circuit generates a first signal of the form Vdc+A sin(2.pi.ft-0.degree.) and a second signal of the form Vdc+A sin(2.pi.ft-90.degree.). The first signal is input to a first error amplifier along with a first sampled difference signal from the motor. The second signal is input to a second error amplifier along with a second sampled difference signal from the motor. The outputs from each of the first and second amplifiers is input into a first comparator and a second comparator along with a sawtooth waveform to create a first sinusoidally modulated square wave signal and a second sinusoidally modulated square wave signal. The first and second sinusoidally modulated square wave signals are fed to driver circuits which in turn control an H-bridge circuit for powering the motor from a DC bus.

Abstract: A multiphase load control system has switches in electrical series within each of several split sources of phase voltage. In each phase of one implementation, two contactor poles are in series between split sections of a secondary winding of a transformer. The contactor poles are part of one or more contactor units, each of which can have a voltage rating significantly less than the phase voltage provided by the system.
