Abstract
A circuit includes first and second phase windings, a direct current (DC) power supply to convert alternating current (AC) power to DC power, at least one power switch between the first and second phase windings, and a controller to control the at least one power switch. The circuit also includes a component to prevent the DC power supply from collapsing when the at least one power switch is on during a first portion of a cycle and a second component to prevent the DC power supply from collapsing when the at least one power switch is on during a second portion of the cycle.
