SOLID STATE SWITCH STUDY.
Abstract
To achieve solid state switch capability beyond the state of the art, new concepts in design, encapsulation evaluation and circuitry of silicon controlled rectifiers were studied. A flat disc-shaped encapsulation was developed which is adaptable to series stacking and reduced space requirements. Triggering methods of the series configurations of thyristors were studied. An opticalelectrical triggering technique was developed and feasibility demonstrated. The circuit utilizes a xenon light source and a light sensitive switch coupled by fibre optic lightguides. A breadboard modulator using these techniques was fabricated and tested successfully. A series stack of six flat packaged thyristors was evaluated as the power switch in the modulator and results were excellent. (Author)
