Abstract

PURPOSE: To omit the floating time to set up the power supply for the system in which the ignition pulse of the thyristor is transmitted via the optical signal by securing the supply of power to the gate circuit through the different power supply circuit.
CONSTITUTION: The power is supplied to power supply circuit 16 from power supply circuit 13 via primary conductor 14 and secondary winding 15 and then to gate circuit 2 of thyristor 1. Conductor 14 and winding 15 form the pierced current transformer. For the ignition pulse, the op]tical signal generated through gate control circuit 3 is sent to photo detector 5 with light guide 4 used as the medium to be converted into the electric signal and them sent to gate circuit 2. And the pulse shaped at circuit 2 is applied to the gate of the thyristor. In this way, the floating time to set up the power supply can be omitted. Furthermore, the loss can be reduced for the thyristor converter, and the pulses featuring the direct current, wide duration or narrow duration can be used as the ignition pulse.
