Abstract: Assembly workability of an electric compressor to which an inverter circuit section and a filter circuit section are attached is improved. The inverter circuit section (3) includes an inverter control board (17), a sleeve assembly (18), and a power module (14). The inverter control board, the sleeve assembly, and the power module are integrated. The filter circuit section (4) includes a filter circuit board (66) and a support member (67). The filter circuit board (66) and the support member (67) are integrated. The inverter circuit section and the filter circuit section are structured to be capable of being stored each individually within an inverter storing section (8) from the same direction and detachably attached to the housing (2).

Abstract: [Problem] An inverter device is provided which is capable of more quickly raising an internal temperature of an electrolytic capacitor within a permissible range of a ripple voltage to shorten a non-operating time. [Solution] The inverter device includes an electrolytic capacitor 1, an inverter circuit 2, a temperature sensor 4, and a control device 3. When the ambient temperature of the electrolytic capacitor 1 detected by the temperature sensor 4 is lower than a predetermined temperature, the control device 3 on-drives specific switching elements of the inverter circuit 2 before the start of a normal operation of a motor 5, and executes a warming up operation of allowing a current capable of controlling a ripple voltage of a DC voltage within a permissible range to flow through the motor 5 at a predetermined rate of increase while keeping the motor 5 stopped.
