A vehicle powertrain includes an IGBT that conducts current between a supply and load. The vehicle powertrain also includes a controller that applies voltage to a gate of the IGBT at a first level for a first duration that depends on a capacitance of the gate, and increases the voltage over a second duration based on a rate of change of the current falling below a threshold defined by a supply voltage for the load.
