Title:
POWER CONVERTER
Document Type and Number:
WIPO Patent Application WO/2018/029928
Kind Code:
A1
Abstract:
Provided is a power converter that converts a DC input voltage to a DC output voltage and outputs the DC output voltage to a load, said power converter including a discharge resistor for discharging charge accumulated in the load, a discharge switch for switching the conduction state of the discharge resistor, and a discharge controller that controls the discharge switch so that the output voltage becomes a predetermined target voltage, wherein the discharge controller controls the discharge switch to interrupt the conduction through the discharge resistor when the output voltage is lower than a predetermined threshold voltage that is higher than the target voltage, and the discharge controller corrects the threshold voltage in response to change in the temperature of the load.
