Shunt regulator at excitation output of generator control unit for overvoltage protection

摘要

An electrical system includes a generator; a generator control unit connected to the generator; and a shunt regulator connected to an excitation output of the generator control unit, wherein the shunt regulator is configured to overload the excitation output of the generator control unit in the event of an overvoltage condition in the electrical system, such that an output voltage of the generator does not exceed a predetermined ceiling voltage during the overvoltage condition.
