Abstract
A circuit includes phase windings, a direct current (DC) power supply, and a power switch circuit. The power switch circuit includes at least one power switch and a voltage regulator in parallel with the at least one power switch, wherein current flows through the voltage regulator when the at least one power switch is on and off. The circuit also includes at least one non-collapsing DC power supply component to prevent the DC power supply from collapsing when the at least one power switch is on and conducting during at least a portion of a cycle. One or more of the DC power supply and power switch circuit may be at a midpoint of the phase windings.
