摘要： PROBLEM TO BE SOLVED: To provide a control method and its control device for an inverter device, capable of downsizing a device for the connection to a power generating system such as for solar light power generation and a commercial power, and also capable of supplying an AC output current of power factor of 1 to the commercial power side. SOLUTION: In a control method for an inverter device, which converts the DC output of a DC power supply and which is connected to an AC power supply, the phase voltage of a commercial power 4 is detected and used as a command signal, and the output current of an inverter device 2 is detected and used as a feedback signal. Then, the command signal is compared with the feedback signal to generate an error signal. A control signal is formed in such a way as to make the error signal zero, and the inverter 2 is controlled based on this control signal.
