Repetitive Switching for Inductive Energy Storage

摘要

This report describes the development and testing of a high current repetitive switch. The objective was to develop a switch capable of repetitively diverting current and energy from an inductive energy store into a load. A mechanical switch employing sliding electrical contacts was built and tested. The switch demonstrated performance exceeding design goals. In an inductive energy storage circuit the switch successfully commutated a current of 7640 A at a repetition rate of 33 Hz. The switch has been operated at repetition rates ranging from 1 Hz to 49 Hz. Over 1600 successful commutations have been achieved with no failures. (Author)
