ABSTRACT:
An abnormality of a generator provided with a plurality of power supply units is easily detected. Each of the power supply units includes each of output windings L1to L4, which are wound independently of each other around the single iron core, and each of rectifier circuits2to5. The power supply units produce an integrated output power. Control means33to35control the rectifier circuits such that an output voltage agrees with a target voltage Vref. In a case where an added up power W becomes a power target value Wref, when the added up current I further increases, a power comparing section39reduces the target voltage Vref to prevent the rectifier circuits from outputting power. Further, when the added up current I exceeds a current upper limit ILMT, a gate pulse is stopped.
