Abstract
A control sectionsupplies a current obtained by rectifying the output of an exciting windingto a field windingresponding to variations in the output voltage of the generator to suppress the variations in the output voltage of the generator. The control sectiondrives a transistorat a duty based on a difference between the output voltage of a main windingand a target voltage and controls the gate voltage of an FETto control a field current to a constant value. A flywheel power generation unit including a control power supply windingis provided as a power source of the control sectionand a power source for passing an initial current through the field windingA current to be supplied to the field windingfrom the flywheel power generation unit is merged with an exciting current via a diode
