Divided Phase AC Synchronous Motor Controller

A circuit for a motor comprising:

• 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 at least approximately at a midpoint of the motor phase windings to receive alternating current (AC) power transferred from one or more of the phase windings and convert the AC power to DC power;
• a first stage power switch circuit comprising at least one power switch outside of the DC power supply and electrically connected at least approximately at a midpoint between the at least two of the phase windings on each half of the circuit;
• a second stage power switch circuit comprising at least one other power switch outside of the DC power supply and electrically connected at least approximately at the midpoint of the phase windings to receive AC power from the motor phase windings;
• a motor controller to control the first stage one power switch circuit and the second stage power switch circuit, the motor controller electrically connected at at least one of (i) at least approximately at the midpoint of the phase windings and (ii) at least approximately at the midpoint between the at least two of the phase windings on each half of the circuit;
• and
• a 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 or the at least one other power switch is on and conducting.
