Beschreibung
Zusammenfassung:	Provided is a power converter for converting a DC input voltage to a DC output voltage and outputting the DC output voltage to a load, including: a discharge resistor which discharges electric charges accumulated in the load, a discharge switch which switches an electric conduction state of the discharge resistor; and a discharge controller which controls the discharge switch so that the output voltage becomes a predetermined target voltage, wherein the discharge controller controls the discharge switch to cut off electric conduction of the discharge resistor when the output voltage is lower than a predetermined threshold voltage that is higher than the target voltage, and wherein the discharge controller corrects the threshold voltage in response to a temperature change of the load.
