Abstract
Inverter control device is provided. First correcting-signal providing unit of the inverter control device provides a signal reflecting an active power correcting signal. Active power control unit of the inverter control device generates an angle control signal reflecting an output voltage phase of an inverter. Second correcting-signal providing unit of the inverter control device provides a signal reflecting a reactive power correcting signal. Reactive power control unit of the inverter control device generates a control signal reflecting an output voltage amplitude of the inverter. Processing unit of the inverter control device receives a feedback signal reflecting an output current of the inverter, a feedback signal reflecting an output voltage of the inverter, the angle control signal, and the control signal, and outputs a signal reflecting the active power of the inverter, a signal reflecting the reactive power of the inverter, and a voltage command signal.
