Description
Summary:— A compact repetitive high-power pulse generator, which could be used for high voltage applications including high power microwave and low temperature plasma, is described. Stray resistances which influence the performance of the generator were discussed and numerically optimized. Then, the high-power pulse generator was built in our laboratory. Experimental results show that pulses with peak power of 30 MW, peak voltage of 87.6 kV, and rise time of 60 μs, approximately, were obtained on a capacitive load of 200 nF. The repetitive rate was 10 Hz and the generator has successfully worked for over 10 000 shots for high voltage applications.
