Abstract
A power conversion device for an electric vehicle includes an inverter that drives a motor mounted in an electric vehicle, and a controller that controls the inverter based on an operation command. The controller includes a sensorless control unit, and corrects an initial resistance value set in the controller, based on temperature information of a temperature sensor mounted in a cooler, sets a resistance value of the motor to the corrected initial resistance value, and causes the sensorless control unit to operate based on the set resistance value.
