PHASE DETECTOR FOR THREE-PHASE POWER FACTOR CONTROLLER ABSTRACT A phase detector (16, 18, 20) is provided for use in a power factor controller for a three-phase induction motor. The power factor controller includes switching thyristors (10,12,14) for each motor phase winding and the phase detector for each phase includes an operational amplifier (A1) which senses the current phase angle for that phase by sensing the voltage across the phase thyristor. Common mode rejection is achieved by providing a positive feedback resistor (R5) between the input and output of the voltage sensing operational amplifier.
