Light-fired thyristor development
Abstract
A high power light-triggered thyristor was developed and demonstrated. A series-connected string of eight such thyristors was tested to show feasibility for commercial utility applications in VAR generator applications. The chief benefit derived from light-triggered thyristors is that a high voltage stack of such thyristors can be switched directly by a light signal transmitted through electrically insulating fiber optics cables. Design considerations applicable to light-triggered thyristors are described and means of optimizing the light source-fiber optic cable system are discussed. A hermetically sealed package for light-triggered thyristors is described. Test results on individual light-triggered thyristors are presented, and the operation of a module consisting of light source, fiber optics cables, and a series string of eight light-triggered thyristors is described.
