Abstract:
1. An integrated-inverter electric compressor, comprising: an inverter unit integrally built into a periphery of a housing containing an electric motor and a compression mechanism, the inverter unit comprising a noise-suppression filter circuit and an inverter circuit; wherein the housing has, on the periphery thereof, an inverter box accommodating the inverter circuit, which includes a power board for converting DC power to AC power and applying the AC power to the electric motor and a control board for controlling the AC power applied to the electric motor, and a junction box which is individually provided with the inverter box, communicates with the inverter box, accommodates the noise-suppression filter circuit, which is provided on a power line for supplying DC power to the inverter circuit; wherein the noise-suppression filter circuit is configured by the plurality of high-voltage components which are electrically connected via a pair of busbars; and wherein the pair of busbars includes branched busbars branched off near connections with a high-voltage component installed close to the inverter circuit, the branched busbars being connected to P-N terminals of the inverter circuit in a communicating section between the junction box and the inverter box.
