Evaluation of Solid State Switches for a Space Based Laser Modulator
Abstract
Several solid state switch candidates were selected and tested to evaluate their capability to serve in a space based laser modulator application. Two of the SCR's tested surpassed the stringent requirements and were operated at 1300-1400 volts and 2500-2775 amperes with a 4 micro S flat-topped pulse. The repetition rate was 6-10 hertz and the turn on di/dt was pushed higher than 16 kA/micro S without failure. A saturable magnetic switch was employed to enhance the di/dt capability and minimize the switch losses. A solid state switch assembly would consist of ~ 30 series connected SCR's. When considering weight, efficiency, life, reliability, etc., the solid state switch concept compares favorably to a baseline thyratron system.
