Theoretical low-energy design of exploding foil initiator

Abstract

In order to promote the development of miniaturization, low-energy and integration of exploding foil initiator, its low-energy design, preparation and tests were studied. It is expected to control the initiation voltage less than 1000 V. Based on the mechanism of bridge electrical explosion and driving flyer, the performance of exploding foil initiator at different parameters of bridge, flyer and barrel was calculated, which indicates an optimal matching relationship among component parameters as the bridge size of 0.2×0.2×0.006 mm, the flyer thickness of 12~22 μm and the barrel hole size of Ф 0.3×200~350 μm.
