Abstract
A generator system arranged to respond to a variation in the load with a generous margin regardless of a change in the output of the generator or the engine due to degradation with the passage of time. The output current of the generator is rectified by a converter composed of thyristors in a bridge configuration of which the direct current output is converted by an inverter into an alternating current at a commercial frequency and connected to a load. The engine speed is controlled so that the conduction angle of the thyristors in the converter can be held at a target degree. As the target degree stays within a range smaller than the maximum limit, the generator runs with a margin, thus readily responding to a variation in the load. When the throttle opening is excessively opened, the target conduction angle is decreased to increase a target speed of the engine, hence inhibiting the engine from being overloaded and running at an excessive higher speed.
