ABSTRACT:
The object is to provide an inverter system for a vehicle-mounted air conditioner capable of reducing standby power requirements during nonuse. The voltage supply from a communication power source80is turned on and off on the basis of a signal from a communication driver27aand an electric switch is changed over, whereby the voltage supply from a vehicle-mounted battery power source50to a DC-DC converter26is turned on and off and the voltage supply to a motor-control microcomputer24and a gate circuit22is turned on and off. As a result of this, during nonuse the operating state of the motor-control microcomputer24is shifted to a sleep mode by performing control by a host ECU60, whereby the voltage supply is suspended and it becomes possible to reduce power consumption.
