Abstract
The present disclosure includes: a gate drive unit which applies a gate drive voltage to a control terminal of a semiconductor switching element so as to drive the semiconductor switching element; a voltage feedback unit which is connected to a high-potential main terminal of the semiconductor switching element and which causes a voltage of the high-potential main terminal to be fed back to the gate drive unit, the voltage being generated when the semiconductor switching element is turned off; and a discharge unit forming a path through which electric charge included in the voltage feedback unit is discharged to the high-potential main terminal side of the semiconductor switching element when the semiconductor switching element is turned on.
