Abstract
A Power Factor Corrector system for use with AC induction motors which detects information from the motor voltage and motor current and decreases the power input to the motor proportional to the detected phase displacement between the current and voltage resulting in reduced electrical power input to the motor as the mechanical load is decreased.
