Beschreibung
Zusammenfassung:	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. The inverter device includes an electrolytic capacitor, an inverter circuit, a temperature sensor, and a control device. When the ambient temperature of the electrolytic capacitor detected by the temperature sensor is lower than a predetermined temperature, the control device on-drives specific switching elements of the inverter circuit before the start of a normal operation of a motor, 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 at a predetermined rate of increase while keeping the motor stopped.
