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 capacitorand a reactorbetween a power source and an inverter board, 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 capacitorand the reactorto a power boardby using a bus bar, the voltage ripple restraining effect is further increased, and the capacitorand the reactorare unitized integrally by the bus barto improve the assembling workability of the power board
