Abstract

Modulating a gate drive current supplied to an output drive switch coupled to an electric motor by performing at least the following: obtain a gate drive current modulation profile, supply, based on the gate drive current modulation profile, a first gate drive current level as the gate drive current when the output drive switch is operating within a first region, drop the first gate drive current level to a second gate drive current level when the output drive switch transitions from the first region to operating within a Miller region, increase the second gate drive current level to a third gate drive current level within the Miller region, and set the gate drive current to a fourth gate drive current level when the output drive switch transitions from the Miller region to operating within a third region.
