Patent ID: 8717765

Claim:
An integrated-inverter electric compressor in which an inverter accommodating unit is provided at the periphery of a housing accommodating an electric motor and a compressor, and an inverter unit that converts DC power from a high-voltage power supply into three-phase AC power and supplies the three-phase AC power to the electric motor is provided in the inverter accommodating unit, wherein the inverter unit includes an inverter module in which a power-system metallic board having mounted thereon semiconductor switching elements is integrated with a plastic case having a plurality of terminals and integrally formed therewith by insert molding, and a CPU board having mounted thereon a control and communication circuit that operates at a low voltage, including a CPU, is provided on a top face of the inverter module, and wherein, inside the plastic case, a thermosetting resin layer for insulation and anti-humidity purposes is provided so as to cover a top face of the power-system metallic board, and a vibration-absorbing elastomeric adhesive layer that maintains a rubber state in an operating temperature range of the electric compressor is provided between a bottom face of the CPU board and the thermosetting resin layer.
