摘要： The present invention relates to an electric compressor with an inverter, in which the inverter for variably regulating the rotating speed of a compressor driving motor is installed in an inverter housing mounted on a compressor housing, wherein said inverter comprises: an upper main board for supplying power to the driving motor; a lower bus bar assembly including a bus bar electrically connected to the main board, and an insulator covering the bus bar; a low power element mounted on the main body; and a high power element which is mounted on the insulator and connected to the bus bar, and which consumes power at a relatively higher rate than the low power element. The electric compressor with the inverter according to the present invention is provided with the bus bar assembly arranged separately from the main board, to thereby integrate the bus bar for applying power to the high power element and reduce the size of the main board as compared to conventional main boards, so as to obtain a compressor with further compact outer dimensions.

摘要： A method for controlling an electric compressor according to the present invention comprises the steps of: (I) starting a compressor by applying a power source to an air conditioner; (II) determining whether the compressor is starting normally; and (III) driving the compressor normally if the compressor is starting normally at step (II), or otherwise restarting the compressor if the compressor is not starting normally and then determining again whether the compressor is starting normally. Therefore, at an early stage of starting the compressor, abnormal operations (breakdown, disconnection, overheating and the like) of the compressor are determined by an inverter to determine restart or operation failure of the compressor, thereby improving the reliability of the electric compressor.

摘要： The present invention relates to a method for controlling an inverter-integrated electric compressor for a vehicle air-conditioning system, and more particularly, to a method for controlling an inverter-integrated electric compressor for a vehicle air-conditioning system which can reduce only the RPM of a motor without stopping an inverter and thus maintain a rated power and torque when a compression load of an air-conditioner is large and an over-current occurs in the inverter, exceeding the torque generated from the motor of the electric compressor, and which can reduce the RPM, which is an angular speed, and increase a torque, and thus continuously providing drivers with a comfortable environment with a vehicle air-conditioner even when the torque of the motor exceeds the maximum level due to overload, and which can reduce risks of the inverter and the electric compressor and thus prevent secondary damage. The method for controlling an inverter-integrated electric compressor for a vehicle air-conditioning system comprises: the first step of calculating a target RPM of a motor for driving an inverter-integrated electric compressor in a vehicle air-conditioning system; the second step of checking whether or not the current applied to the motor driven according to the target RPM exceeds the threshold value preset in a control unit; and the third step of performing a feedback control for reducing the target RPM and reducing the current if the current applied to the motor exceeds the threshold value, and of rotating the motor according to the target RPM if the current does not exceed the threshold value.
