    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： A method for controlling an electric compressor into which an inverter for controlling an electric motor as a drive source is integrally incorporated. The method is characterized by comprising the steps of acquiring the temperature of an accessory of the inverter, when the acquired temperature becomes or is already equal to or higher than the maximum rated temperature of the accessory, calculating the value of a current which can flow at the acquired temperature and restrictively controlling the rotational speed of the electric compressor such that the input current becomes equal to or less than the value of the current which can flow, and when the temperature of the accessory becomes lower than the maximum rated temperature, releasing the restrictive control. The method for controlling the electric compressor can prevent a malfunction of the accessory even in use under a high-temperature environment while preventing increase in the cost and size of the electric compressor by preventing an increase in the size of the accessory of the inverter.
