A novel flux compression/dynamic transformer technique for high-voltage pulse generation

Abstract

The paper presents the basic concepts that underlie an EPSRC funded research activity initiated at Loughborough University. A novel technique is described that enables the so termed shock wave driven flux compression process to be performed inside a laboratory, without the use of any high-explosive charge, and results from preliminary proof of principle experiments are analysed. Details of the necessary ancillary equipment, such as fast (TA/s) generators, electric guns, high voltage resistors, high voltage vacuum helical transformers and specific transducers are presented, together with a study of the dielectric/metallic phase transition in aluminium powder. The paper concludes by showing how the different concepts can be combined, leading to a high-voltage pulse generator with a fast-rising output.
