Coaxial magnetic pulse compression system to generate fast‐rising pulsed power

Abstract

A fast-rising pulsed power generator (PPG) using a coaxial magnetic pulse compression (MPC) system has been developed. Two kinds of magnetic cores, a Co-based amorphous metal and a nanocrystalline Fe-based soft magnetic metal, have been used in the coaxial MPC system to evaluate losses of magnetic cores and leakage current of a saturable inductor. The PPG produced a pulsed-high-current of 3.7 kA with a risetime of 7 ns (20-80%) at a repetition frequency of 1000 pulses per second.
