An electronic circuit is provided for regulating a three-phase generator which includes: a circuit for sensing the average of the three-phase voltages; a circuit for sensing the highest phase voltage; and a circuit for sensing the highest phase current. The output of each of these circuits is compared to reference currents which represent an average voltage setting and high phase voltage and current limits, and an error signal is generated that is integrated over time. The integrated error signal is utilized as input to a comparator circuit which generates a pulsewidth modulated signal that represents deviation from the desired operating parameters. The pulsewidth modulated signal is applied to an output amplifier circuit which in turn serves to control the current through the generator\s exciter field. An exciter field current detector is connected between the output amplifier and the input of a gain and compensation circuit in order to provide a negative current feedback circuit to minimize transients. In addition, connections to both the input of the integrator and the input of the gain and compensation circuit are provided so that reactive load division with other generators may be facilitated.
