Claim:
1. A circuit comprising: phase windings; a direct current (DC) power supply at least approximately at a midpoint of the phase windings to receive alternating current (AC) power from the phase windings and convert the AC power to DC power; a power switch circuit comprising at least one power switch at least approximately at the midpoint of the phase windings to receive AC power from the phase windings; a first non-collapsing DC power supply component connected to the DC power supply to prevent the DC power supply from collapsing when the at least one power switch is on and conducting during a first portion of a cycle; and a second non-collapsing DC power supply component connected to the DC power supply to prevent the DC power supply from collapsing when the at least one power switch is on and conducting during a second portion of the cycle.
