Abstract
An engine operated generator is arranged to constantly respond to a change in the load with a margin of power. The output current of the generator 1 driven by an engine 2 is rectified by a converter 3 composed of a thyristor bridge structure. A direct current released from the converter 3 is converted by an inverter 4 to an alternate current at a commercial frequency and connected to a load 5. A thyristor driver circuit 9 controls the conduction of thyristors so that the voltage at the input of the inverter 4 is constant. A fuel flow controller 10 detects the conduction angle of the thyristors and the revolution of the engine 2 is controlled so that the conduction angle is converged on a target conduction angle. Since the target conduction angle is set within a predetermined range smaller than the maximum conduction angle, the generator is maintained with margins of its output and can thus provide a stable level of voltage and respond quickly to a change in the load.
