A single phase inverter device of the present invention, capable of converting DC power into AC power, includes: a voltage control part controlling a voltage of DC power inputted from the outside; a first switching inverter part converting the power, controlled by the voltage control part, into AC power; and a second switching inverter part converting the power, controlled by the voltage control part, into the AC power when the first switching inverter part does not perform the conversion. At this point, the first switching inverter part includes a PWM type switching inverter, and the second switching inverter part is able to operate during the off-duty of PWM control.
