    摘要: A motor-driven compressor according to the present invention is formed with a housing that contains a compression portion and a motor for compressing refrigerant. The compressor housing further is provided with a suction housing for introducing the refrigerant. A capacitor is provided for smoothing a current that is supplied from a power source to the motor. The capacitor is in contact with the suction housing. In such motor-driven compressors, because the capacitor is in contact with the suction housing, heat transfer from the capacitor to the housing may effectively be facilitated. In further embodiments of the present invention, the capacitors may be disposed on various portions of the suction housing and in various orientations relative to an axial direction of the motor-driven compressor. These selected orientations reduce the dimensions of the motor-driven compressor.

    摘要: An electric compressor control device includes: an inverter for electric compressor motor; a communication microcontroller arranged in a low-voltage region for transmission of an instruction signal via a high-speed communication bus; and a control microcontroller arranged in a high-voltage region and connected to the communication microcontroller via an insulation element for transmitting the instruction signal from the communication microcomputer as an inverter control signal to the inverter. The power voltage of the communication microcomputer is supplied from a low-voltage power source. The voltage from the low-voltage power source is transformed via a transformer and supplied as a power voltage of the control microcontroller. Thus, it is possible to use the existing insulation element at an insulation boundary between the low-voltage region and the high-voltage region so as to surely supply a predetermined power voltage to the microcontroller for controlling the inverter, thereby improving the communication reliability of the entire control device.
