An inverter device includes a converter circuit that rectifies a first alternating current output from a power supply to generate a rectified current, a capacitor that stores therein the rectified current and outputs a direct current based on the rectified current, and an inverter circuit that converts the direct current into a second alternating current for driving a load. Moreover, a voltage control unit generates and outputs, during a period when any one of an instantaneous power cut and an instantaneous voltage drop occurs in the power supply, a first current command based on a voltage of the capacitor and a second current command; and a current control unit generates and outputs, based on the first current command, the second current command for controlling the inverter circuit to output the second alternating current.
