タ装置の制御装置。 A power outage detection circuit for detecting a power outage of the AC power source in an inverter device that converts an AC power source into a DC power source using a rectifier circuit, and converts the DC output back to AC power using an inverter circuit connected via a smoothing capacitor to drive a motor. and a control power supply circuit connected to the DC main circuit of the inverter device, which lowers the output frequency of the inverter circuit in response to a power failure detection signal from the power failure detection circuit to generate regenerative power from the motor. A control device for an inverter device, wherein a terminal voltage of a smoothing capacitor connected to the DC main circuit is secured by electric power, and control is performed by receiving power from the control power supply circuit.
