Abstract

This article focuses on the development and evaluation of a high-voltage switch composed of two gas discharge tubes (GDTs) as a cost-effective alternative to traditional triggered spark gaps used in exploding foil initiator systems (EFIS). Through multi-physics simulations and experimental tests, the study demonstrates that the two GDTs break down successively under a single positive high-voltage trigger pulse, with the switch exhibiting a linear increase in peak current relative to applied voltage and a nearly constant resistance after closing. The addition of parallel GDTs showed minimal impact on current amplitude. Validation using micro-electro-mechanical system (MEMS)-fabricated micro-chip metallic bridge foils confirmed that the switch can reliably induce foil explosion, supporting its feasibility for EFIS applications.
