摘要
A system and method are provided for controlling a three-phase pulse-width-modulated alternating-current voltage regulator, in order to reduce inrush current when starting, for example, a large three-phase induction motor. The system and method include a set of four-quadrant switches connected in a converter circuit between the input voltage and the output load. By applying certain switching states in a determined sequence based on sensed values of the input voltage at the three lines, the system and method synthesize a three-phase variable magnitude output voltage from the three-phase input voltage of fixed magnitude.
