Abstract
A vehicle powertrain has a power inverter that includes a load switch with a main emitter and a current mirror emitter, a variable resistor coupled between the current mirror emitter and the main emitter, and a controller. The controller may be configured to adjust a gate voltage based on a voltage across the variable resistor, and responsive to the gate voltage exceeding a Miller plateau gate voltage, increase a variable resistor resistance such that feedback increases as the load switch saturates.
