Claim 2:
3. The power conversion device according to claim 1, wherein
the output circuit includes an overheat detection circuit that is configured to detect a junction temperature of a switching device that performs switching operation to execute the power conversion operation and configured, when the detected junction temperature exceeds a predetermined first threshold temperature, to output the operation stop signal to the power supply stop circuit, and
the overheat detection circuit is configured to stop the power supply from the internal power source to the microcomputer, when the junction temperature exceeds a predetermined second threshold temperature, which is set to be higher than the first threshold temperature, even if the status signal notifies that the microcomputer is in the power shutdown inhibit period.
