Evaluation of Solid State Switches for a Space Based Laser Modulator

reportActive / Technical Report | Accession Number: ADA639452 | Open PDF

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 SCRs 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 didt was pushed higher than 16 kAmicro S without failure. A saturable magnetic switch was employed to enhance the didt capability and minimize the switch losses. A solid state switch assembly would consist of 30 series connected SCRs. When considering weight, efficiency, life, reliability, etc., the solid state switch concept compares favorably to a baseline thyratron system.
