ABSTRACT:
A method and apparatus for improving the efficiency of operation of polyphase AC induction motors. The method and apparatus utilizes a microprocessor to tune a motor control system such that time interval on at least two phases of a multi-phase power source such that the time intervals between turn-on of bi-directional switches and the time of sensing the resultant inrush currents of the two phases on two motor stators are maintained substantially constant as the load is varied.
