Pagination or Media Count:
RAVEN, a 5 kJ, 1.5 MV repetitive pulser, was built to test the performance of high voltage transformer pulse-charging systems. The pulser has a 4 nF water-insulated, pulse-forming line which is charged by a bipolar primary capacitor bank through a voltage step up pulse transformer. Both the primary capacitor and high-voltage output switches are gas dynamic spark gaps which have been operated at sustained pulse rates up to 20 pps. The system operates with an overall energy transfer efficiency slightly better than 90. A description of the system and its performance characteristics will be discussed. Specific design features of the switches and transformer will also be included.
