TEMPERATURE PROTECTION DEVICE
A temperature protection device includes temperature detection devices detecting the temperatures of switching elements and a control device controlling the switching elements. The control device stops driving of a first switching element the temperature of which rises to an overheat detection tempe...

| description | A temperature protection device includes temperature detection devices detecting the temperatures of switching elements and a control device controlling the switching elements. The control device stops driving of a first switching element the temperature of which rises to an overheat detection temperature and resumes the driving of the first switching element when the temperature of the first switching element drops to a return temperature. The control device controls timing of resuming the driving of the first switching element so that an undriven time period of the first switching element is longer in a case where at least one of the switching elements other than the first switching element is in a high load state when the temperature of the first switching element reaches the overheat detection temperature than that in a case where all the switching elements other than the first switching element are in a low load state. |
