Abstract

A circuit for a motor comprises at least two phase windings forming one half of motor phase windings of the circuit and at least two other phase windings forming another half of the motor phase windings of the circuit. A direct current (DC) power supply receives alternating current (AC) power transferred from one or more of the motor phase windings and converts the AC power to DC power. A first stage power switch circuit comprising at least one power switch is connected between the at least two phase windings on the one half of the motor phase windings of the circuit and between the at least two other phase windings on the other half of the motor phase windings of the circuit. A second stage power switch circuit comprising at least one other power switch is connected between the one half of the motor phase windings of the circuit and the other half of the motor phase windings of the circuit, the at least one other power switch to receive AC power from one or more of the motor phase windings. At least one non-collapsing DC power supply component prevents the DC power supply from collapsing when the at least one power switch is on.
