Abstract
The object is to provide a technology enabling appropriate driving of an IGBT. A driving circuit is a driving circuit that drives an IGBT by controlling the gate voltage of the IGBT, and includes a first charging capability and a second charging capability. The first charging capability increases the gate voltage up to a threshold voltage of the IGBT, and a second charging capability increases the gate voltage beyond the threshold voltage. An increase in the gate voltage with the first charging capability per unit time is higher than an increase in the gate voltage with the second charging capability per unit time.
