079172-BWE POWER FACTOR CONTROL SYSTEM FOR INVERTER-DRIVEN A-C INDUCTION MOTOR Abstract: The power factor in an inverter-driven induction motor is held relatively constant at a desired optimum value, despite variations in mechanical loading on the motor, by monitoring (27,28) the d-c bus current to determine the ratio of real and reactive currents, thereby to detect the actual power factor. The actual and desired power factors are then effectively compared (31-42) and the resulting error signal is fed back to the inverter's d-c power supply to adjust the inverter output voltage to change the reactive current to the extent necessary to maintain the desired power factor.
