PROBLEM TO BE SOLVED: To reduce the loss in wiring of an inverter device and reduce the possibility of disconnections in wiring by making the wiring to be able to be simplified and, at the same time, to improve the versatility of the device. SOLUTION: An inverter device has an enclosure 23, a power device 26 which is provided in the enclosure 23 and driven with a current supplied from a main power source, a first heat sink which is positioned on the bottom wall of the enclosure 23 and discharges the heat generated when the device 26 is driven to the atmosphere, a power source for auxiliary machine provided in the enclosure 23 and actuates an auxiliary machine with a prescribed voltage, and a second heat sink which is positioned on the side wall 51 of the enclosure 23 and discharges the heat generated when the power source for auxiliary machine is driven. Since the power source for auxiliary machine is housed in the enclosure 23, the wiring of the inverter device can be simplified. In addition, the loss in the wiring is reduced and the possibility of occurring disconnection in the wiring is reduced by shortening the wiring section through which a high-voltage direct current flows on the outside of the enclosure 23. |
