Abstract
An object is to achieve overheat protection for a converter and stable voltage output thereof. This power supply device includes: a converter connected to power supply voltage and having a plurality of switching elements; a temperature detection circuit for detecting a temperature of the converter; an inverter which is connected between the converter and a load, and which converts output voltage of the converter and outputs resultant voltage to the load; and a control unit for controlling the switching elements of the converter. When the temperature detected by the temperature detection circuit has exceeded a first limitation value, the control unit controls the switching elements so that the output voltage of the converter becomes the power supply voltage at a set change rate.
