Vehicle-air-conditioner electric compressor

A vehicle-air-conditioner electric compressor in which an inverter unit is integrated with a housing accommodating an electric motor and a compression mechanism, the inverter unit being configured such that a high-voltage ground circuit area for driving the electric motor and a low-voltage ground circuit area for control and communication are isolated from each other,

• wherein a lead-out position of a low-voltage cable and a connector for supplying a low voltage from a low-voltage power supply to the low-voltage ground circuit is provided either in a side surface opposite to a mounting position of a high-voltage component and a high-voltage cable for supplying a high voltage from a high-voltage power supply to a power system circuit on the high-voltage ground;
• or at an end farthest away from the mounting position of the high-voltage cable and the high-voltage component in an adjacent side surface or the same side surface,
• wherein the mounting position of the high-voltage component is disposed only along a side surface in the high-voltage ground circuit area.
