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. This modulation of current flow (or lack thereof) regulates the magnetic field strength inside the alternator to produce a stable voltage over a wide range of RPMs.
