Completely Explosive Ultracompact High-Voltage Pulse Generating System

A conventional pulsed power technology has been combined with an explosive pulsed power technology to produce an autonomous high voltage power supply. The power supply contained an explosive-driven high-voltage primary power source and a power-conditioning stage. Two types of ultracompact explosive primary power sources were used, one of which was based on the physical effect of shock wave demagnetization of high- energy ferromagnets, and the other one was based on shock wave depolarization of high-energy ferroelectric materials. The volumes of the energy-carrying ferroelectric elements in the shock wave ferroelectric generators (FEGs) varied from 1.2 to 2.6 cm³. The volume of the energy-carrying ferromagnetic elements in the shock wave ferromagnetic generators (FMGs) was 8.75 cm³ for all tests performed. The power-conditioning stage was based on the spiral vector inversion generator (VIG). The combined FEG-VIG and FMG-VIG systems demonstrated successful operation and good performance. The output voltage pulse amplitude of the combined FEG-VIG system exceeded 90 kV, with risetime of 6.8 ns.
