Abstract
An AC voltage regulator provides a desired AC voltage to a load. The desired AC voltage is within a predetermined range above and below that of an AC voltage source. The AC voltage regulator has a transformer, the secondary winding of which is configured to be placed in series with the AC voltage source and the load. A plurality of switches is configured to direct current from the AC voltage source through the primary winding of the transformer. The switches are further configured to control the direction in which current flows through the primary winding of the transformer. A pulse width modulator controls the switches according to a desired cycle period.
