Abstract
Atmospheric pressure plasma discharge excited by repetitive nanosecond pulsed voltage has high reactive ability.A repetitive nanosecond pulse generator was designed based on the modularized avalanche transistor Marx circuit and transmission line transformer (TLT).The delay time and jitter of output pulse waveform of different Marx modules were calculated.The impacts of magnetic cores quantity,position and dimension on the output pulse amplitude were analyzed.The pulse combination efficiency of TLT was remarkably improved by increasing the induction,increasing the ratio of outer diameter to inner diameter of magnetic cores and adopting magnetic cores on the first and top stages.Utilizing both the direct combination and TLT,the amplitude of output pulse was further improved.The generator can produce 2～14kV pulses into 50～300W resistive load and 4～25kV pulses into high impedance load,where the pulses have 3.8ns rise time,7～15ns pulse width and 0～ 10kHz repetitive frequency.The output parameters of the compact generator can be adjusted flexibly.关键词
