A control device for a system interconnection inverter. The control device includes an active/reactive current reference generator and an active/reactive current detector for detecting an output AC current of the inverter. The control device further includes a phase detector, a frequency detector, and a voltage amplitude detector of the AC voltage of the inverter. The control device also includes a frequency reference generator and a voltage amplitude reference generator. The control device also includes a frequency correction computing circuit and a voltage amplitude correction computing circuit. The control device further includes an adder for adding the active current reference signal and the voltage amplitude correction signal to output as an active current correction reference signal, and for adding the reactive current reference signal and the frequency correction signal to output as a reactive current correction signal. The control device still further includes a current control circuit for generating an output voltage reference signal for the inverter and a gate control circuit for controlling the output voltage of the inverter based on the output voltage reference signal.
