Abstract

PURPOSE: To make it possible to design a circuit easily and also to prevent malfunction by using a thyristor with a large current amplification factor and a pulse transformer at the side of the direct current power supply of a plant.
CONSTITUTION: Output permit signal S1 and clock signal SC are supplied to input terminals I1 and I2 and then applied to pulse transformers 20 and 21 via transistors Tr18 and Tr19. Then, the output terminal of transformer 20 is connected to the gates of thyristors 27 and 28 and driving signal S0 is outputted from output terminal O via diode 29, thereby driving the operation terminal of the plant. On the other hand, Tr30 repeats the ON-OFF operation synchronizing with clock pulses from AND gate 17 so as to control thyristors 27 and 28. Consequently, transformers 20 and 21 and thyristors 27 and 28 with large current amplification factors are used at the direct-current power supply side of the plant to desigh the circuit easily and also to prevent malfunction.
