The generator has a multiplicity of windings for producing output power from the generator by a magnetic coupling that provides output power DC voltage. An out regulator circuit provides variable DC voltage that is maintained within the allowable range for connected loads as the flywheel slows during discharging. The output regulator circuit includes electronic switches for switching connections of the windings to change the number of windings connected to the output to maintain output power DC voltage within the allowable range. The switching occurs less than once per every 10 revolutions of the flywheel. | |
