Abstract
An inverting apparatus and a control method thereof are provided. The inverting apparatus includes an inverting circuit, a capacitor, and a control circuit. The inverting circuit receives a DC input power and is configured to convert the DC input power into an AC output power, wherein an AC output current of the AC output power is preset to a preset output current. The capacitor is connected to an output terminal of the inverting circuit. The control circuit is coupled to the inverting circuit and is configured to control a power conversion of the inverting circuit, wherein the control circuit superimposes a preset capacitor compensation current of which the phase leads to the preset output current on the preset output current, so as to control the inverting circuit to adjust the AC output current and provide the adjusted AC output current to a power grid.
