A hybrid electric vehicle includes a traction battery, traction motor and power inverter therebetween. The power inverter converts the DC power of the traction battery to AC power to drive each phase of the traction motor. The power inverter includes Insulated Gate Bipolar junction Transistors (IGBTs) to modulate the power to the traction motor. The speed at which the IGBTs are modulated impacts the system performance including power loss, voltage overshoot and current overshoot. Using a dual emitter IGBT to provide a current mirror of the drive current, circuitry may be used with the gate drive circuitry such that the gate drive speed may be dynamically adjusted based on characteristics including temperature and traction motor rotational speed.
