  • Gate driving with phased slew rate control and overcurrent protection
    Patent number: 12261605
    Abstract: A vehicle, slew rate control circuit and method of operating an electric motor of a vehicle. The slew rate control circuit is between a gate driver of the vehicle and an inverter of the vehicle. The slew rate control circuit includes a first branch between the gate driver and the inverter, wherein the inverter provides an electrical signal output to an electric motor of the vehicle, and a second branch between the gate driver and the inverter in parallel with the first branch, wherein current flows through the first branch during a first time period and through the second branch during a second time period, wherein the flow of the current controls a slew rate of the electrical signal output by the inverter to the electric motor.
