Solid State Power Controllers (ISEM-2A).

Abstract : This report covers an engineering study to determine the optimum DC power controller configuration for ISEM-2A modules. The study indicates that two 10 amp. or four 5 amp. controllers can be mounted on one ISEM-2A frame, and that each 10 amp. unit will have a predicted reliability of nearly one million hours before failure. Mounting of DC controllers using existing technology is discussed, and thermal performance of various frame material is tabulated and evaluations made. Finally, methods of circuit simplification using recently developed components, LSI and advanced packaging techniques which reduce cost, increase reliability and improve manufacturability are described.
