Pulsed power generation using ferromagnetic circuits

Results are presented of an experimental study of the generation of high-voltage pulses in generators designed as open and closed ferromagnetic circuits. Experiments were carried out using a light gas gun system. The magnetic projectiles were composed of NdFeB discs having 1.27 and 2.54-cm diameters. Data are given for the effects on the amplitude of high voltage pulses by the length and velocity of the ferromagnetic projectiles and the design of the generating unit for both high voltage and high current modes of pulsed power generation. A detailed analysis is presented on the specific features of pulse power generators using open and closed ferromagnetic circuits. Fundamental limitations due to the physical processes occurring in systems like these are determined.
