A generator voltage regulator circuit is provided with a switching circuit for alternatively connecting or disconnecting a generator exciter field winding to a DC power source. A discharge circuit is provided for conducting current, produced by a collapsing magnetic field in the exciter winding following disconnection of the winding by the switching circuit, in a revese direction through the DC power source. A driving circuit controls the switching circuit with a series of turn-on pulses. Each of the turn-on pulses is initiated in response to a transition in a clock signal and is terminated alternatively when the current in the exciter field winding reaches a predetermined magnitude or when a second transition occurs in the clock signal. This invention also encompasses a method of regulating exciter field current performed by this circuit.
