A power converter 18, which is configured to perform cooling of a switching element by using a boiling cooling apparatus that makes use of a boiling phenomenon of a coolant incorporated therein, includes a control unit 17 to control an operation of the power converter 18 based on a deviation between an element attachment surface temperature Tf, which is a temperature of an attachment surface of the switching element, and a cooling apparatus intake air temperature Ta. When the deviation between the element attachment surface temperature Tf and the cooling apparatus intake air temperature Ta exceeds a predetermined threshold, the control unit 17 performs control of stopping the power converter 18. |
