Abstract

See full text

A switching control device controls a drive circuit including one or more series circuits each one of which includes an upper switching element and a lower switching element. The switching control device includes an upper side temperature detection unit detecting a temperature of the upper switching element (hereinafter, “an upper side temperature”), a lower side temperature detection unit detecting a temperature of the lower switching element (hereinafter, “a lower side temperature”), and a signal generation circuit adding an offset value to a command voltage of a PWM signal output to the upper and lower switching elements to generate and output a PWM signal to the switching elements so that the upper and lower side temperatures approximate to each other.
