摘要： The present invention has an object to provide an on-vehicle air conditioner that can prevent breakage or the like caused by applying a high voltage. In an inverter system 20 that controls an operation of a motor 30 of a compressor for the on-vehicle air conditioner, a motor control microcomputer 24 operates by converting a voltage supplied from an on-vehicle battery power source 50 into a low voltage. Thus, the motor control microcomputer 24 is operated to perform failure diagnosis of a high voltage circuit Cb without a high voltage power source 40 being turned on. The failure diagnosis can be performed without power being supplied from the high voltage power source 40 to the high voltage circuit Cb, thereby preventing the high voltage circuit Cb from being broken by applying the high voltage even when there is some failure in the high voltage circuit Cb.

摘要： There is provided an apparatus for controlling an electric compressor, which can actuate the electric compressor rapidly through a simpler and lower-cost configuration while achieving reduction in weight, cost, and assembling time of the electric compressor. In the case where a pressure difference between the inlet side and the outlet side of the compressor body is present when a motor of the electric compressor is actuated, the motor is actuated at a number of revolutions lower than that in the normal mode. Thereby, even if a refrigerant has been liquefied on the outlet side of the compressor body, for example, the motor can be actuated by performing such action as to push out the liquefied refrigerant. In this case, the number of revolutions of the motor is increased by being changed stepwise or linearly, by which the number of revolutions of the motor is caused to reach a required number of revolutions as early as possible while surely performing the actuation.

摘要： The present invention has an object to provide a control device for an electric compressor and a start control method of an electric compressor that can smoothly and reliably start the electric compressor even at high temperature. Even in a high temperature state of a power transistor, a rotational speed or an acceleration rate of a motor according to the temperature is set to gradually start the electric compressor. After the commencement of the start, the temperature of the power transistor is repeatedly checked for every predetermined time to update the rotational speed or the acceleration rate of the motor, and the rotational speed or the acceleration rate of the motor is increased according to the temperature of the power transistor, thereby allowing quick start. When a refrigerant starts to flow in a housing of the electric compressor with the start, a control board is cooled and the temperature of the power transistor decreases, and thus a synergistic effect can be obtained.
