基于方波LTD的3MV闪光照相驱动器设计
Design of 3 MV flash radiographic driver based on square pulse LTD
摘要
Abstract
Linear transformer driver (LTD) is a new electrical circuit topology developed in recent years which has a num-ber of significant advantages such as compactness,flexible output parameters and high energy transfer efficiency.According to the requirement for flash X-ray radiography,the pulsed driver which can deliver 3 MV on a 40 Ω rod pinch diode (RPD) has been designed.The machine is composed of 30 square pulse LTD stages in series with a total length of 8 meters.Each LTD stage con-tains 12 fundamental bricks each consisting of two 10 nF capacitors and a multi-gap switch connected in series and 4 harmonic bricks each consisting of two 1 nF capacitors and a multi-gap switch connected in series.The transformer oil is used as voltage ad-der insulator.According to the equivalent circuit simulation,the generator can produce more than 3 MV fast pulse in 16.8 ns with 98 ns FWHM.关键词
