Abstract
Leading current or lagging current of an alternator is supplied by a simple structure including short-circuit switch elements. The short-circuit switch elements are connected across output terminals of the alternator three-phase armature windings, and are turned on and off at fixed timings to supply a suitable amount of the leading current to armature windings regardless of the rotational speed. Thus, the leading current can be supplied without phase-leading-capacitors so that the apparatus can be made compact, lightweight and powerful. Even if any of the short-circuit switch elements can not turn off, the battery discharge can be prevented.
