20090246047 | Integrated-inverter electric compressor - An integrated-inverter electric compressor whose grounding effect and grounding reliability are increased by reliably grounding an inverter device to a housing and in which the size the inverter device are reduced by simplifying the grounding structure is provided. The integrated-inverter electric compressor includes an inverter device provided in an inverter container on the outer circumference of a housing. The inverter device includes an inverter module formed by integrating a power-related metal substrate and a resin case and is provided with a control-related substrate on the upper surface of the inverter module; the resin case is integrated with mounting legs provided at a plurality of locations on the circumference; the mounting legs are grounded to the power-related metal substrate and the control-related substrate; and grounding terminals, which frame-ground the substrates to the housing, are insert-molded in such a manner that the grounding terminals are securable to the inverter container with screws. | 10-01-2009 |
20090263255 | APPARATUS AND METHOD FOR CONTROLLING ELECTRIC COMPRESSOR - 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. | 10-22-2009 |

20100232982 | CONTROL DEVICE FOR ELECTRIC COMPRESSOR AND START CONTROL METHOD OF ELECTRIC COMPRESSOR - 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. | 09-16-2010 |
