Generator

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;
• voltage detecting means that detects an output voltage of each of the rectifier circuits;
• current detecting means that detects an output current from each of the rectifier circuits;
• control means that controls the rectifier circuits so as to make the output voltage converge at a target voltage;
• power judgment means that detects that an added up power computed from an added up value of the output currents of the respective rectifier circuits detected by the current detecting means and from the target voltage becomes a predetermined value of power;
• and
• target voltage reducing means that reduces the target voltage for a more increase in the added up current of the output currents when the power judgment means detects that the added up power becomes the predetermined value of power.
