Abstract
An excitation winding () and a field winding () are provided. A smoothing capacitor () smoothes a current of the excitation winding () and inputs it to the field winding (). A transistor () is driven to control an output of the generator winding (). A diode () prevents a field current from flowing in a reverse direction. A transistor () connected to the diode () is driven in a phase reverse to a phase of a drive signal of the transistor (). A duty monitordetermines whether a duty ratio of the drive signal of the transistor () is larger than a reference duty ratio, and when the duty monitordetermines that the duty ratio of the drive signal is larger than the reference duty ratio, an unit () extends an output cycle of the drive signal by thinning out the drive signal.
