The current mode of pulsed power generation in moving magnet systems

Results are presented of investigations of the generation of high-current pulses in moving magnet generators designed as an open ferromagnetic circuit. The experimental study was performed with the use of a light gas gun. The magnetic projectiles were ferromagnetic cylinders having 2.54-cm diameters. Data are given for the amplitude of high current pulses and power in the load for different designs of the devices, the effect of various windings on the pulse-generating coils, and different types of loads. It has been shown that with velocities of the magnetic projectiles of 200-300 m/s, the peak current of the pulses produced by the generators reach kiloamperes.

I. INTRODUCTION

The moving magnet generator is an electro-mechanical energy converter of the type adapted for converting high-magnitude input pulses of mechanical energy into peak output pulses of electrical energy. In our previous publication [1] we have reported initial results of an experimental study of the generation of high-voltage and high-current pulses by generators designed as open ferromagnetic circuits and closed ferromagnetic circuits. In this paper results are presented of detailed investigations of the current mode of pulsed power generation with an open ferromagnetic circuit design.
