Abstract
An electric compressor includes an electric motor, and a motor controller configured to drive the electric motor. The motor controller includes a high voltage circuit board on which switching elements are mounted, a low voltage circuit board on which a control circuit controlling switching operation of the switching elements is mounted, an input connector, an output connector, and a current sensor. The high voltage circuit board and the low voltage circuit board are stacked with each other. The output connector is integrated with a detection busbar that provides electrical connection between the high voltage circuit board and the low voltage circuit board, and through which detection signals indicative of the output current are output to the control circuit.
