A power failure detection unit in an AC-DC converter device detects power failure of a 3-phase AC power supply at the time of driving a motor, and generates a power failure detection signal in accordance with detection of power failure. A transmitter unit in the AC-DC converter device transmits the power failure detection signal using a cable, radio, or an optical fiber. A receiver unit in a DC-AC converter device receives the power failure detection signal transmitted from the transmitter unit.
