Abstract: An auto-regulated motion power system apparatus that may be used to generate usable electricity from disparate energy sources includes a combination of a variable frequency alternator driven by a primary mover and coupled to a load. An energy control module includes a closed-loop feedback system coupled to a pulse width modulation controller and a switch mode rectifier. The alternator has a modulated control signal input having the ability to vary in frequency and voltage with an output having a controlled voltage and varying frequency. The switch mode rectifier accepts variable AC voltages from the alternator and outputs a constant predetermined DC voltage both to one side of the windings of the alternator and to a first side of a high frequency switch. An output on the pulse width modulation generator is connected to a switch control so that when the switch is closed, current flows through the windings of the alternator and when the switch is open, no current flows through the windings.
