INTEGRATED ELECTRIC COMPRESSOR
First Claim
1. An integrated electric compressor comprising:
- a compressor constituting an air conditioner;
a motor for driving the compressor;
a control board for controlling the operation of the motor; and
a housing for accommodating the compressor, the motor, and the control board, characterized in thatthe integrated electric compressor further comprises a ripple reducing circuit which is provided between a power source for applying a voltage to the motor and the control board to reduce ripples of a voltage supplied from the power source, wherein the ripple reducing circuit comprises a capacitor and a reactor, andthe ripple reducing circuit is connected to the power source side and the control board by a bus bar.

Abstract
There is provided an integrated electric compressor having a circuit configuration capable of decreasing the size thereof while restraining current ripples. In an inverter of the electric compressor, by providing a capacitor 13 and a reactor 14 between a power source and an inverter board 12, the ripples of a driving voltage is restrained, and a motor can be driven with high efficiency and the size of a housing can be decreased. Further, by connecting the capacitor 13 and the reactor 14 to a power board 16 by using a bus bar 23, the voltage ripple restraining effect is further increased, and the capacitor 13 and the reactor 14 are unitized integrally by the bus bar 23 to improve the assembling workability of the power board 16.
