Abstract:
Systems, apparatus, and methods for operating inductors in a Z-source inverter in a continuous current mode are provided. One system includes an AC motor, a Z-source inverter, and a processor. The inverter is configured to provide current and reactive power to the AC motor. The processor is configured to monitor the current and instruct the inverter to provide a greater amount of reactive power to the AC motor if the current is below/equal to a threshold amount. An apparatus includes means for determining if current produced by the inverter is below/equal to a threshold amount, and means for altering voltage commands supplied to the inverter so that an AC motor is induced to draw additional reactive power. One method includes determining if a plurality of inductors are providing a threshold current amount, and inducing a motor to draw more reactive power if the current is below/equal to the threshold amount.
