A motor driven generator has a generator control unit which incorporates a programmed microprocessor to control generator operation. A generator voltage regulator utilizes the microprocessor of the generator control unit to develop an error voltage which is added to the average phase voltage of the generator, controlling the generator field current. In the event of a phase failure the generator control unit senses an abnormally high phase voltage condition, disables the average phase voltage circuit. In the event of an abnormal difference between the high and low phase voltages, the gain of the error signal circuit is reduced.
