INVERTER-INTEGRATED ELECTRIC COMPRESSOR

摘要

The purpose of the present invention is to provide an inverter-integrated electric compressor that has improved inverter device assemblability with respect to a housing, allows for improved productivity and reduced manufacturing costs, and allows an inverter device, and thus the electric compressor itself, to be made more compact and lightweight. Provided is an inverter-integrated electric compressor (1), wherein an inverter device (7) is provided with a resin structure (12) formed as a single unit with a housing section for high-voltage system components and a circuit board assembly section, and by assembling a power system circuit board, a control system circuit board (15), a busbar, a plurality of high-voltage system components that make up the inverter device (7), and the like onto the resin structure (12), the inverter device (7) is made into a unit (34) and this unit (34) is assembled onto and integrated with the inverter housing section (8).
