Abstract:
To improve the accuracy of detecting a current flowing through an electric compressor after operation of the electric compressor, the electric compressor having a large change in temperature before and after operation. An inverter-integrated electric compressor ( 1 ) that compresses and discharges a refrigerant suctioned therein, includes an inverter device ( 2 ) provided with a circuit board ( 60 ) mounted with an inverter circuit ( 40 ), the inverter device ( 2 ) being integrally incorporated in an inverter case. The circuit board ( 60 ) is provided with a current detection circuit ( 30 ) that detects an input current flowing through the inverter circuit ( 40 ), and an offset correction circuit ( 20 ). The current detection circuit ( 30 ) includes a shunt resistor ( 32 ) that is serially connected to the inverter circuit ( 40 ) and detects a current, and a first amplifier ( 31 ) that amplifies and outputs a voltage appearing as a voltage drop in the shunt resistor ( 32 ). The offset correction circuit ( 20 ) includes a second amplifier ( 21 ) that performs an offset correction of the first amplifier ( 31 ). The first amplifier ( 31 ) and the second amplifier ( 21 ) are integrated into a single integrated circuit.

Claim (Index 3):
The inverter-integrated electric compressor according to  claim 2 , wherein:\n the first amplifier, the second amplifier, the resistor included in the first peripheral component, and the resistor included in the second peripheral component of the current detection circuit and the offset correction circuit are mounted on a same plane of the circuit board and provided to a same ground plane.
