A power converter may include a plurality of power conversion circuits, a plurality of temperature sensors, and a controller. Each of the power conversion circuits may include a switching element. The plurality of power conversion circuits may be connected in parallel. Each of the temperature sensors may measure a temperature of one of the switching elements. The controller may select the power conversion circuit to be driven in an ascending order of the temperatures of the switching elements measured by the temperature sensors based on a supplied current value Iin supplied to the power converter.
