Abstract

The MAPPS (MegAmpere Pulsed Power Supply) demonstration tests are described, and the results are reviewed. The observed limits to the switch performance and methods to improve performance are discussed. Testing of the 100 kA demonstrator was completed in July 1986. The measured transformer coupling during operation was 0.99. The switch successfully interrupted 460 A and developed 7.5 kV at five commutations per second. Leakage current through the gate-turn-off thyristor prevented the switch from reaching the 1000 A design goal. The switch performed well up to 460 A, commutating current 290 times during testing. Results indicate that energy storage transformers provide a method to store energy at low currents so that high-purity aluminium or superconducting conductors can be used
