Use of inductive energy storage for electric pulse destruction ofsolid materials

An inductive energy storage switch system for the destruction of solid materials is reported. This is based on creating a pulsed electric breakdown in the solid dielectric, which then propagates in the specimen. This scheme provides a higher destruction effectiveness compared to a capacitive energy storage system. The higher energy efficiency is attributed to a different discharge behavior during the discharge build-up in the solid material. A higher applied voltage causes a breakdown of a larger number of voids in a heterogeneous solid dielectric. The energy transfer to partial discharges, when using the inductive storage system, is faster than for the capacitive energy storage system, due to a shorter risetime of the discharge current
