Abstract

PURPOSE: To improve generation efficiency, productivity and maintainability by a constitution wherein a control means controls each regulator based on the generating state of each generator detected through a generating state detecting means so that the output voltage from each generator is regulated.
CONSTITUTION: When the generating power of a first generator is higher than that of a second generator, an electromotive force corresponding to the differential output current is induced in a coil 11 and then it is converted into a predetermined voltage level which is further converted into an absolute value and fed to the noninverted input terminal of a comparator 14. The comparator 14 outputs a control signal based on that voltage and a sawtooth voltage. The control signal causes a transistor 21 to turn OFF while a transistor 23 to turn ON thus conducting the exciting coil 17 of the second generator. When the transistor 21 is turned OFF, the transistor 22 is turned ON while the transistor 23 is turned OFF thus bringing the exciting coil 17 into nonconducting state.
