Experimental study on one-stage magnetic pulse compression system

A magnetic pulse compression system which does not contain external remagnetization circuits commonly used in magnetic compressors is presented. Principle of operation for the compressor is described. Simulation of pulse compressor working on a 500 Ω resistive load illustrates that in order to realize the desired pulse, 6 ms and 500 ns magnetization period would be required for cores of saturable pulse transformer and magnetic switch, respectively. The one-stage compression system delivers a -18.5 kV, 70 ns pulse width across a 200 Ω load with a fall time of 40 ns and a repetition rate up to 500 Hz. To improve the matching, the inductor in parallel with load is replaced with a fast-recovering HV diode. The experiment shows that the pulse voltage reverse amplitude and damped oscillation d
