摘要： A motor-driven compressor has a housing and a partition. A compressing portion and an electric motor as the drive source of the compressing portion are accommodated in a first area. A drive circuit for the motor is arranged in a second area so as to have dissipation of the drive circuit. The compressor further includes a conductive member electrically connected to the circuit and fixed to the partition, and an electrical connection portion electrically connecting the conductive member to the motor. The connection portion is partly received in a passing area formed between the housing and the motor. The housing has a suction port and a discharge port. The discharge port is located at a position farther from the partition than the suction port and the passing area. An insertion member in the passing area restricts flow of refrigerant in the housing toward the discharge port via the passing area.

摘要： An inverter device includes a filter circuit, an inverter circuit, an electric current detecting circuit, a voltage detecting circuit, a control circuit for outputting a drive signal so as to switch switching devices, and an internal power supply. The control circuit includes a shutdown circuit for stopping outputting the drive signal to the switching devices when an electric current flowing through a motor is an overcurrent or a voltage across the inverter circuit is an overvoltage or the voltage outputted from the internal power supply is not stabilized. When electric power by residual charge in the capacitor is used after the inverter device is disconnected from a high-voltage battery, the control circuit generates the drive signal based on a reference waveform and three commands for keeping switching devices corresponding to one phase in either ON or OFF state and for switching ON and OFF the other remaining switching devices.
