Abstract

PURPOSE:To prevent an overexcitation, by charging or discharging a condenser according to an output frequency of a generator, converting a terminal voltage into a control signal against an overexcitation whenever the terminal voltage of the condenser surpasses a set value and giving it to an exciting device. CONSTITUTION:An amplifier 12 gives to a thyristor 6 for excitation through a relaxation oscillating circuit 13 a generator terminal voltage from a voltage detecting circuit 7, a field terminal voltage from a stabilizing circuit 11 and a deviation signal of output and normal voltage from a V/F detector 14. A condenser C5 of the V/F detector 14 is charged or discharged according to an output frequency of a generator. Whenever the voltage of the condenser C5 surpasses the normal voltage, a condenser C6 is charged for the period, and the voltage of the condenser C6 is given to the amplifier 12 in the form of an overexcitation signal.
