Claim:
1. An inverter control device comprising: a first correcting-signal providing unit configured to receive a frequency setting signal and provide a signal reflecting an active power correcting signal; an active power control unit configured to receive the signal reflecting the active power correcting signal, an active power setting signal, and a signal reflecting an active power of an inverter to generate an angle control signal reflecting an output voltage phase of the inverter; a second correcting-signal providing unit configured to receive a voltage setting signal and provide a signal reflecting a reactive power correcting signal; a reactive power control unit configured to receive the signal reflecting the reactive power correcting signal, a reactive power setting signal, and a signal reflecting a reactive power of the inverter to generate a control signal reflecting an output voltage amplitude of the inverter, wherein the control signal reflecting the output voltage amplitude of the inverter is a voltage amplitude control signal; and a processing unit configured to receive a feedback signal reflecting an output current of the inverter, a feedback signal reflecting an output voltage of the inverter, the angle control signal reflecting the output voltage phase of the inverter, and the control signal reflecting the output voltage amplitude of the inverter to generate the signal reflecting the active power of the inverter, the signal reflecting the reactive power of the inverter, and a voltage command signal.
