An improved method and system of increasing the effective electrical load capacity of a power converter is disclosed. Potential damage due to current surges from variation in load is avoided by sensing an impending over-current condition, decreasing the system output by a predetermined amount or to a predetermined level, and then gradually increasing the output to bring the system back to desired operating conditions. Such control can be affected by varying the throttle setting to adjust rotor speed, controlling the DC rail level, or a combination of both methods.

[ We claim:] [1.] A method of increasing effective electrical load capacity of an apparatus for converting mechanical energy into electrical energy at respective output terminals, the apparatus including an engine and a generator, the method comprising the steps of:sensing the occurrence of an output current in excess of a predetermined level;responsive to the occurrence of an output current in excess of the predetermined level,decreasing the output voltage of the generator to a predetermined lower value, and gradually increasing the output voltage from the predetermined lower value until the voltage reaches a predetermined set point value,wherein the step of decreasing the output voltage comprises:decreasing the engine speed to a predetermined level, maintaining the engine speed at the predetermined level for a predetermined time period, then gradually increasing the engine speed.
