First Claim
1. A motor control system for controlling the operation of a motor (210), the motor control system powered by a constant frequency input power source (800) via a conductor system (810), comprising:
- a reactive power reducing input power system (1300) in electrical communication with the motor (210) and the constant frequency input power source (800), via the conductor system (810);
wherein the reactive power reducing input power system (1300) includes an AC-DC converter (640) and a regulator system (650), wherein the regulator system (650) is in electrical communication with a DC-AC inverter (670) in electrical communication with the motor (210); and
wherein the reactive power reducing input power system (1300) accepts at least two different alternating current voltage power inputs including a first alternating current voltage and a second alternating current voltage, and the regulator system (650) produces a single direct current voltage from either the first alternating current voltage or the second alternating current voltage, and transmits the direct current voltage to the DC-AC inverter (670).

Abstract
A motor control system powered by an input power source. The system includes a reactive power reducing input power system in electrical communication with a motor and a constant frequency input power source. The reactive power reducing input power system includes an AC-DC converter and a regulator system, wherein the regulator system is in electrical communication with a DC-AC inverter that is in electrical communication with the motor. The system may include an isolation system to electrically isolate the DC-AC inverter from the motor when the DC-AC inverter is not transmitting power to the motor. The system may accept multiple alternating current voltage sources including both single phase and three phase sources.
