AC power generating apparatus and method

摘要

Reverse current is supplied from a battery (9) to armature coils (5a-5c) of a three-phase synchronous power generator (100), via semiconductor switching devices (11a-11f) of a three-phase full-wave rectifier (11), by controlling the switches (11a-11b). By this control, the reverse current will reduce waveform distortion of armature current of each phase so as to reduce the electromagnetic force pulsation and, therefore, reduce vibration or noise. <IMAGE>
