ABSTRACT:
A detecting means easily detects the abnormality of a generator having a plurality of power supply units. Each of the power supply units includes one of a plurality of output windings L1to L4, which are wound independently of each other around single iron core, and one of rectifiers2to5that are provided in correspondence to the output windings and produces an integrated output. Controllers33to35control the rectifiers such that the output voltage corresponds with a target. A voltage deviation judgment section37outputs the abnormal signal when one of the output voltages of the rectifiers2to5is different from remains. A current deviation judgment section39outputs the abnormal signal when one of the output currents of the rectifiers2to5is different from remains. When the abnormal signal is detected, the outputs of the rectifiers2to5are stopped.
