An inverter device includes: a rectifier circuit (4) that converts an AC power supply into a DC power supply; a smoothing unit (5) that is connected to a subsequent stage of the rectifier circuit; a short-circuit unit (3) that short-circuits the AC power supply via a reactor (2) that improves a power factor of the AC power supply; an inverter unit (6) that converts a direct current from the smoothing unit into an alternating current; and a control unit (11) that controls the inverter unit, wherein a gate drive circuit (14) is connected to a gate terminal of each switching element (12) in the inverter unit, the gate drive circuit includes a first gate voltage line (22) and a second gate voltage line (23) having a voltage value larger than a voltage value of the first gate voltage line, and the voltage value of the first gate voltage line is variable even during an operation of the inverter device. |
