Title:
インバータ装置
Document Type and Number:
Japanese Patent JP5925425
Kind Code:
B2
Abstract:
The present invention includes: an electrolytic capacitor that smoothes a rectified voltage to a direct voltage; an inverter circuit that generates an alternating voltage from the direct voltage, to drive an electric motor; a controlling device that controls drive of switching elements included in the inverter circuit; and a temperature measuring device that measures a temperature of the electrolytic capacitor, to output the measured temperature to the controlling device, in which, when the temperature obtained by the temperature measuring device is lower than a predetermined target temperature, the controlling device supplies the electric motor with a current which is restricted so that a ripple voltage of the direct voltage falls within an allowable range, before starting a normal operation of the electric motor, so that the temperature of the electrolytic capacitor is raised to the target temperature. Thus, the electrolytic capacitor can be used even in a lower-temperature environment.
