    摘要： An inverter includes an upper ECU, a communication microcomputer receiving an instruction from the upper ECU, a motor control microcomputer receiving an instruction from the communication microcomputer, a gate driving circuit controlled by the motor control microcomputer, and a switching element driven by the gate driving circuit for converting a direct current of a high-voltage battery into an alternating current to drive a motor. The communications between the upper ECU and the communication microcomputer is performed according to a CAN protocol. The communications between the communication microcomputer and the motor control microcomputer is performed according to a low-speed serial communication protocol. An insulation boundary is defined between the communication microcomputer and the motor control microcomputer to isolate a low-voltage side electric component receiving electric power of the low-voltage battery from a high-voltage side electric component receiving electric power of the high-voltage battery. And, a photo coupler is disposed on the insulation boundary to assure insulation and transmit signals.

    摘要： In an electrical compressor having a motor and an electrical circuit integrated with a compression portion, a part of electrical components of the electrical circuit is disposed in spaces between a cylindrical outer surface of a motor housing and an imaginary flat surface that imaginarily contacts the cylindrical outer surface. Therefore, the spaces can be used effectively, and the electrical compressor can be downsized. Further, the part of the electrical components can be effectively cooled by refrigerant in the motor housing. On the other hand, the outer surface of the motor housing is used as one surface defining an inner space of a casing for accommodating the electrical circuit. In this case, the electrical circuit can be effectively cooled by refrigerant in the motor housing.
