Abstract
An inverter driver of an air conditioner drives an inverter of an actuator that actuates the air conditioner. The inverter driver includes a drive circuit outputting a drive signal to the inverter, a microcomputer controlling the drive circuit, a first mechanical relay connected to the drive circuit, and an inverter control power supply continually supplying power to the microcomputer. The first mechanical relay is capable of cutting off an inverter drive power supply of the drive circuit or cutting off the drive signal of the drive circuit. The first mechanical relay cuts off the inverter drive power supply of the drive circuit or the drive signal of the drive circuit when an abnormality in the air conditioner has been sensed and stopping the driving of the actuator has been requested.
