<P>PROBLEM TO BE SOLVED: To provide an inverter system for an in-vehicle air conditioner capable of suppressing standby power during no use. <P>SOLUTION: By turning on and off voltage supply from a communication power source 80 based on a signal from a communication driver 27a, an electric switch is changed over to turn on and off voltage supply from an in-vehicle battery source 50 to a DC-DC converter 26 and to turn on and off voltage supply to a motor control microcomputer 24 and a gate circuit 22. Hence, during no use, control of a higher-order ECU60 allows the motor control microcomputer 24 to be shifted to a sleep mode before stopping of voltage supply, thus suppressing power consumption. <P>COPYRIGHT: (C)2009,JPO&INPIT |
