Completely Explosive Autonomous High-Voltage Pulsed-Power System Based on Shockwave Ferromagnetic Primary Power Source and Spiral Vector Inversion Generator

摘要

Novel explosive and conventional pulsed-power technologies were combined, and a series of explosive-driven high-voltage power supplies was designed, built, and tested. The power supply contained an explosive-driven high-voltage primary power source based on the fundamental physical effect of shockwave demagnetization of$hboxNd_2hboxFe_14hboxB$high-energy ferromagnet and a power-conditioning stage. The volume of the energy-carrying ferromagnetic elements in the shockwave ferromagnetic generators (FMGs) was 8.75$hboxcm^3$. The power-conditioning stage was based on the spiral vector inversion generator (VIG). The combined FMG–VIG system demonstrated successful operation and good performance. The output-voltage pulse amplitude of the combined FMG–VIG system exceeded 40 kV, with a rise time of 6.2 ns. The methodology was developed for digital simulation of the operation of completely explosive FMG–VIG system. Experimental results obtained are in a good agreement with the results of digital calculations performed.
