Abstract
A switching element control device for controlling a switching element incorporating a reverse conducting diode is provided. The switching element control device includes: a voltage detection circuit detecting a voltage across first and second main electrodes of the switching element; a comparator circuit comparing the voltage detected by the voltage detection circuit with a threshold voltage; and a drive circuit controlling driving of the switching element. The comparator circuit controls the drive circuit so that an on signal is not provided to the switching element when the detected voltage exceeds the threshold voltage.
