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.
