摘要： Methods and apparatus are provided for dynamic voltage control of electric motors. An inverter provides an output voltage to an electric motor based on a gate voltage. The method includes determining a speed of the electric motor and modifying the gate voltage based on the speed of the electric motor. The apparatus includes a gate drive circuit and a controller coupled to the gate drive circuit. The gate drive circuit provides a gate voltage to a switch network, and the switch network produces the output voltage in response to the gate voltage. The controller modifies the gate voltage based on a speed of the electric motor.
