Abstract

A self-commutated solid-state switch has been developed for use as an opening device for an inductive energy store. 25 kA, 5000 V operation has been obtained in a compact switch module. The switch topology is a compact switch module. The switch topology is a two-stage hybrid consisting of an SCR-FET/SCR-IGBT (insulated gate bipolar transistor) combination. The switch is designed to charge an inductive energy store and repetitively commutate the current to a dynamic load. A 25 kA switch module has been built and tested on a battery test stand at General Atomics. The theory of operation, circuit topology, and test results are given
