ABSTRACT OF THE DISCLOSURE A voltage regulator is described adpated for use controlling the output of an AC generator. A voltage control field-winding excitation control circuit supplies direct current to the generator field in response to a driver. The driver, in turn, is operated in response to a switching regulator. A frequency sensing means generates a voltage proportional to the frequency of the generator. This frequency sensitive voltage is combined with a reference voltage to drive an asynchronous switching regulator. The switching regulator produces a train of output voltage control signals to operate the driver. Perferably power MOSFETs are used to control the flow of current to the generator field. Loss of voltage and high current protection features are included.
