Abstract
Disclosed is a drive circuit-integrated electric compressor, which is adapted to cool a power semiconductor element in a motor drive circuit with good efficiency without increasing the temperature of sucked refrigerant gas and while suppressing increase in pressure loss in a path for cooling. Specifically disclosed is a drive circuit-integrated electric compressor into which a motor drive circuit having a power semiconductor element is incorporated integrally, characterized in that the electric compressor is configured so that the power semiconductor element in the drive circuit is cooled by refrigerant gas to be discharged.
