<p>An engine driven multi-phase generator has a 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 average phase output voltage error which is added 97 to the average phase voltage of the generator, and used for controlling the generator field current. In the event of a phase failure the generator control unit senses an abnormally high phase voltage condition, and disables the average phase voltage circuit by opening a switch 115. In the event of an abnormal difference between high and low phase voltages, the gain of the error signal circuit is reduced by opening a switch 114 in parallel with a resistor 131. <IMAGE></p> |
