PROBLEM TO BE SOLVED: To provide a device for driving a switching element which increases the accuracy of determination of whether or not to perform a power saving process of limiting the drive of a switching element S*# (*=c,u,v,w; #=p,n).SOLUTION: A high voltage system comprises: a temperature-sensitive diode SD*#; and a drive IC 20 having a first comparator 38 and a first power supply 40. The configuration transmits a signal conveying a result of determination of whether or not an output voltage Vf of the temperature-sensitive diode SD*# is below a first threshold voltage Vth1 to a control device 14 of a low voltage system via an interface 18 including a photo-coupler 41. |
