Abstract
Official abstract text for this publication.
Unique motor drive apparatuses, systems and methods are disclosed. One exemplary embodiment is an apparatus comprising an AC-DC power supply structured to couple with and drive an electric motor. A sampling and switching device is coupled with the power supply. The switching device is configured to sample an electrical condition of a plurality of power line inputs and to selectably connect the power supply with the plurality of power line inputs. A controller is operatively coupled with and structured to control the switching device in a first mode in which the controller determines a power at which to operate the motor based upon which of the plurality of power line inputs receives power and a second mode in which the controller provides power factor correction of the motor and selects the power line inputs connected to the AC-DC power supply by the sampling and switching device.
