Abstract
An improved system and method for generating high Voltage within an ESAD munition fuze is provided. Conventionally, high voltage transformer conversion circuits used within ESAD munition fuzes utilize a flyback, or step-up transformer. The use of a flyback, or step-up transformer reveal technical limitations when used for the application of increasing arm charge times, voltage conversion efficiency, and power conversion efficiency for ESAD munition fuze applications. Alternatively, the use of a high voltage inductor conversion circuit utilizing an inductor, in combination with a switching transistor allows for a new and improved low cost method for improving ESAD munition fuze applications with respect to generating high voltage from a low voltage source onto a detonator firing capacitor to trigger a Low Energy Explosive Foil Initiator (LEEFI) within an ESAD munition fuze.
