Abstract: A slew rate controllable system for powering an electric machine. The system may include a plurality of power transistors operable for converting a direct current (DC) input into an alternating current (AC) output suitable for electrically powering the electric machine. The system may further include a gate drive system operable for controlling a slew rate associated with transitioning the power transistors between the opened and closed states.

Abstract: A slew rate controllable system for powering an electric machine. The system may include a plurality of power switches operable for converting a direct current (DC) input into an alternating current (AC) output suitable for electrically powering the electric machine. The system may include a gate drive system operable for controlling a slew rate associated with transitioning the switches between opened and closed states.
