Abstract
A control system for a generator for regulating the field current received from an exciter includes a phase control regulator circuit which produces an output voltage having a duty cycle which is proportional to the generator output signal. An oscillator circuit is responsive to the output signal of the phase controlled regulator circuit and produces a pair of controlled circuit pulses whose duty cycle varies accordingly. Control circuit pulses from the oscillator circuit are coupled via a coupling transformer to a rotating current control circuit which controls the generator field current supplied from the exciter in accordance with the oscillator control pulses.
