Blumlein Lines Solid-state Pulse Generator Using High-Efficiency and High-Resistance Stacked
摘要
Abstract
Based on the standard coaxial cable,a high-impedance compact stacked Blumlein lines solid-state pulse generator is developed.The theoretical and experimental studies are conducted with the objective of improving the voltage efficiency.The effect of coupled transmission lines on the output voltage efficiency of stacked Blumlein lines is analyzed by using transmission line theory and discharge equivalent circuit,and simulated by using numerical simulation software for two structures of outer-cylinder discharge type and inner-cylinder discharge type.The simulated results show that the impedance of coupled transmission lines are the main factor causing the loss of voltage gain and the decrease of energy efficiency.The increase of coupling impedance can improve the amplitude of the output voltage and the quality of the waveforms.The inner-cylinder discharge type structure can reduce the number of coupled transmission lines,thus improving the voltage superposition efficiency.At the same time,adopting the spiral coiled winding method of winding and core isolation to increase the coupling impedance can further improve the voltage superposition efficiency of stacked Blumlein lines.Based on the inner-cylinder discharge type structure and core isolation method,a ten-stage stacked Blumlein lines pulse generator is developed and experimentally tested.The test results show that with the charging voltage of 489 V,the output waveform is obtained on the resistance of 1 000 Ω,with an output voltage of 4.56 kV,a rising time of 21 ns,a pulse width of 75 ns.The overall system voltage efficiency is up to 93.3% ,effectively testing the method of pulse stacking efficiency improvement.关键词
