ELECTRIC COMPRESSOR

摘要

An electric compressor (10) comprises: a boost converter (18) for boosting the voltage output from a DC power supply (16); an inverter (20) for converting the power boosted by the boost converter (18) to an AC power; and a motor (14) for rotating the electric compressor (10) by the AC power output from the inverter (20). In the electric compressor (10), the boost converter (18) and the inverter (20) are provided on the same board, housed in the same inverter case, and cooled by a refrigerant flowing into the electric compressor (10). The electric compressor (10) is thereby obtained in which the device size can be prevented from increasing even if the boost converter (18) for boosting a low voltage from the DC power supply (16) is installed.
