Patent ID: 7183668

Claim:
A generator comprising: a plurality of power supply units which are independent respectively and each of which has one of a plurality of output windings that are wound independently of each other around a single iron core and each of which has a rectifier circuit including a rectifier device with control terminals connected to respective phases of one of the plurality of output windings, wherein the plurality of power supply units are connected in parallel so as to integrate their outputs into one output; current detecting means that detects an output current of each of the rectifier circuits; current judgment means that examines each of the output currents detected by the current detecting means and outputs a current abnormality detecting signal when a difference between one of the output currents and at least one of the other remaining output currents is larger than a predetermined value; and output stopping means that stops outputs of all of the rectifier circuits in response to the current abnormality detecting signal.
