ABSTRACT:
Power factor control of a pulse width modulated inverter supplied permanent magnet motor is achieved by using Park Vectors for automatically adjusting a pulse width modulating signal for approximately unity power factor, thereby avoiding the heretofore required manual adjustment during operation of the motor for power factor changes in accordance with changes in EMF and motor resistance.
