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. The circuit also includes a control circuit to control the power switch circuit. The control circuit includes a logic control shut off circuit to shut off the control circuit when the motor is at synchronous speed. 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.
