Abstract: Methods and systems for controlling an electric motor are provided. An electric motor controller is configured to be coupled to an electric motor. The controller includes a rectifier, an inverter coupled to the rectifier, and a control unit coupled to the inverter. The rectifier is configured to rectify an alternating current (AC) input voltage to produce a pulsed direct current (DC) voltage that drops to approximately zero during each cycle when the AC input voltage transits zero. Energy is stored on a load coupled to the motor when AC input voltage is available. The inverter is configured to receive the DC voltage and to provide a conditioned output voltage to the motor. The control unit is configured to manage energy transfer between the motor and the load such that the motor generates positive torque when the DC voltage supplied to the inverter has approximately 100% voltage ripple.

Abstract: An electric motor controller and methods of determining which input power line of a plurality of input power lines of a motor drive controller has been energized are provided. An electric motor controller configured to be coupled to an electric motor includes a plurality of power input lines configured to receive an alternating current (AC) input voltage from an AC power source, an energized line detection device configured to sense that a power input line has been energized by the AC power source, and configured to output an isolated signal, and a rectifier configured to convert the AC input voltage having a frequency to a direct current (DC) voltage. The controller also includes a computing device coupled downstream from the energized line detection device and configured to determine which input power line has been energized.
