多级谐振充电的Marx脉冲源研究
Marx Pulse Source with Multistage Resonant Charging
摘要
Abstract
Marx generator is a classic pulse power generator.In order to better meet the practical needs of high voltage,bipolar and high efficiency,a multi-stage resonant charging Marx pulse generator is proposed,which uses a series resonant charging power supply and a series core magnetic ring transformer to charge the Marx pulse generator in groups.The Marx pulse generator with multi-stage resonant charging of two symmetrical structures is built and its performance is verified,including the unipolar generator and the bipolar pulse generator with variable polarity.The circuit consists of a group of 3-way 8-stage Marx with positive polarity and a group of 3-way 8-stage Marx with negative polarity,totaling 48 stages.The experimental results show that the unipolar Marx generator with variable po-larity can generate positive or negative voltage pulses of 30 kV,and the bipolar generator can output±10 kV voltage pulses to no-load and 50 kΩ resistive load.Through the signal control of Field Program Gate Array(FPGA),the repetition frequency can be adjusted within the range of 1 Hz~1 kHz,the pulse width can be adjusted within the range of 1~200 μs,and the front and back edges of the pulse are within 50 ns.The relaxation time between positive and negative pulses is 0.2~200.0 μs.关键词
