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 μs and 500 ns magnetization period would be re-quired 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 duration are reduced drastically.
