Abstract

An inverter control device (100) is provided. A first correcting-signal-providing-unit (110) of the inverter control device provides a signal (∆P) reflecting an active power correcting signal. An active power control unit (120) of the inverter control device (100) generates an angle control signal (⊖e) reflecting an output voltage phase of an inverter. A second correcting-signal-providing-unit (130) of the inverter control device provides a signal reflecting a reactive power correcting signal (∆Q). A reactive power control unit (140) of the inverter control device generates a control signal (E) reflecting an output voltage amplitude of the inverter. A processing unit (150) of the inverter control device receives a feedback signal (io) reflecting an output current of the inverter, a feedback signal (vo) reflecting an output voltage of the inverter, the angle control signal (⊖e), and the control signal (E), and outputs a signal (P) reflecting the active power of the inverter, a signal (Q) reflecting the reactive power of the inverter, and a voltage command signal (OUT).
