  • Patent number: 9960725
    Abstract: An electric compressor comprises: a boost converter configured to boost a voltage output from a direct current power supply; an inverter configured to convert the power boosted by the boost converter to an alternating current power; and a motor configured to rotate the electric compressor using the AC power output from the inverter. In the electric compressor, the boost converter and the inverter are provided on the same circuit board, housed in the same inverter case, and cooled by a coolant flowing into the electric compressor. The electric compressor is thereby obtained in which the device size can be prevented from increasing even when the boost converter configured to boost a low voltage from the DC power supply is installed.
