Abstract

A power conversion device includes a power semiconductor switching device and a drive circuit. The power semiconductor switching device is configured to supply constant power to a load by switching and to be turned on and off by a control signal from an external control circuit. The drive circuit is configured to detect an operating temperature of the power semiconductor switching device and drive the power semiconductor switching device according to a result of the detection. The drive circuit includes a temperature detecting unit configured to receive the control signal from the external control circuit and detect the operating temperature of the power semiconductor switching device at timings according to the control signal.
