ELECTRICALLY DRIVEN COMPRESSOR INTEGRAL WITH INVERTER

摘要

A high-performance, small-sized inverter device achieved by mounting a common-mode coil in the device without an increase in the plan area of an inverter receiving section. An electrically driven compressor (1) integral with an inverter has the inverter receiving section (4) located on the outer periphery of a tubular housing (2), and the inverter device (20) is placed in the inverter receiving section (4). The inverter device (20) is made up of elements including an inverter board (21), high-voltage components such as a smoothing capacitor (23), an inductor coil (24), and the common-mode coil (30), a terminal base (26) to which a high-voltage cable is connected, and a bus bar assembly (32) forming electric wiring between the electric elements described above. An externally extending section (9) extending externally from one end of the tubular housing (2) is provided at the inverter receiving section (4), and the terminal base (26) is provided at one side of the externally extending section (9). A coil placement section (12) for placing the common-mode coil (30) is integrally formed at the lower part of the terminal base (26) so as to extend downward.
