<p>PURPOSE:To eliminate requirement for using the circuit component parts of high tension resistance, and lower a cost by smoothing the output of the respective thyristor bridge circuits according to respective output windings, with a superimposed circuit, to be superimposed in series, and by controlling gate input voltage to enable output voltage to be stably kept. CONSTITUTION:In an AC generator 1, the same stator core is wound up with a plurality of independent output windings L1, L2, and a control winding L3 separated independently from them, and according to the respective output windings L1, L2, a plurality of thyristor bridge circuits 2, 3 are connected to each other, and the output of the respective thyristor bridge circuits 2, 3 is smoothed by a superimposed circuit 4 and is superimposed in series. Besides, the gate input voltage of the thyristor bridge circuits 2, 3 is controlled, and the output voltage is stably kept by a control circuit 9. Then, the output voltage of the superimposed circuit 4 is contrived to be converted to the AC voltage output of specified frequency by an inverter circuit 5. As a result, even if an output voltage specification is changed, the circuit component parts of high tension resistance and large capacity resistance are not required to be used.</p> |
