MINITURIZED HIGH DENSITY CAPACITOR FOR EFI AND RELATED APPLICATIONS

AN EXTREMELY HIGH ENERGY DENSITY CAPACITOR FOR A FIRE SET TO DRIVE EXPLODING FOIL SLAPPER DETONATOR AND OTHER POWER CONDITIONING EQUIPMENT IS PROPOSED. THE DESIGN INTEGRATES THE HIGH ENERGY STORAGE FILMS (KUREHA/PENWALT) WITH INTEGRATED CIRCUIT TECHNIQUES (PHOTORESIST TYPE DIELECTRIC RELAXATION COATINGS) TO INCREASE THE ACTUAL WORKING FIELD TO APPROACH THE BREAKDOWN FIELD. THE PRECISE FIXED CHARGE AND DISCHARGE DURATIONS ALLOWS THE USE OF RESIST COATINGS ON FOIL EDGES AND OTHER LOCATIONS. THE RESISTIVITY GRADIENTS PRODUCE A VOLUME CHARGE DISTRIBUTIONS WHICH PREVENTS FIELD ENHANCEMENT AT EDGES AND IMPERFECTIONS RESULTING IN A MORE COMPACT CAPACITOR. FURTHERMORE, AN INTERCONNECTION APPROACH IS USED THAT MINIMIZES CURRENT CROWDING AT THE OUTPUT. THIS CONNECTION APPROACH DRASTICALLY REDUCES THE CURRENT DENSITY, MAGNETIC AND ELECTRIC FIELD, HEATING, AND CONDUCTIVE FOIL THICKNESS.
