The Design of Trigger Circuit for Power Thyristor

Abstract:

In this paper, for the strong electromagnetic interference environment, a kind of 6500V/1000A thyristor controller is designed. The controller includes a main trigger state detection module, an optical fiber communication module, a temperature detection module, a main controller module, and a trigger module. It highlights the thyristor trigger circuit and its corresponding detection circuit, this trigger circuit can provide a strong trigger pulse to ensure a reliable triggering of thyristors at any moment, the detection circuit can improve the reliability of the system.
