Abstract: An electric motor controller is configured to be coupled to an electric motor. The controller is also configured to control the electric motor to produce torque when direct current (DC) link voltage has a 100% voltage ripple, or when direct current (DC) link voltage is one of approaching zero and equal to zero, for the purpose of reducing torque ripple in the electric motor.

Abstract: An electric motor controller is configured to be coupled to an electric motor. The controller includes an inverter and a control unit coupled to the inverter. The inverter is configured to receive an input voltage and to provide a conditioned output voltage to the electric motor. The control unit is configured to control the electric motor to produce positive torque when direct current (DC) link voltage has a 100% voltage ripple. Methods for controlling an electric motor using the electric motor controller are also provided.
