SOLID STATE SWITCH STUDY.
Abstract
To achieve the objective of a solid state switch for handling 300 KV, new concepts in device design, encapsulation, evaluation and circuitry are being studied. Basic thyristor samples with periphery gates to enhance fast turn-on have been made. A flat disc-shaped encapsulation to minimize lead inductance and capacitance is employed; and models of both molded plastic and ceramic versions were assembled. Examples of heat radiator and stacking methods are illustrated. A thyristor test set capable of evaluating device properties for radar modulator application has been designed and constructed. Electricaloptical triggering of a series configuration of thyristors was demonstrated and design limitations calculated and discussed. (Author)
