Abstract
A power converter including a control circuit configured to output a control signal, and a semiconductor module. The semiconductor module includes a semiconductor chip, a switching device provided on the semiconductor chip, the switching device being configured to be turned on and off in response to the control signal, and a first temperature sensor configured to detect a temperature of the semiconductor chip. The control circuit is configured to monitor a thermal resistance of the semiconductor module based on a first temperature detected by the first temperature sensor, a second temperature corresponding to a temperature of the semiconductor module, and a power consumption of the switching device.
