Electrical parameter online adjustable high power pulse forming line and electrical parameter adjustment method

Abstract

The invention discloses a high power pulse forming line with electrical parameters adjustable online, which is designed to solve the problem that the core parameters of the prior pulse forming lines are unable to be adjusted. The invention comprises the pulse forming line, a container for a mixed liquid medium, a container for a liquid medium of deionized water, a container for a liquid medium of ethyl alcohol, an air circulation pump, fluid pipelines, a dielectric constant measuring apparatus, two programmed switches and a processing module. The processing module is a computer installed with calculating software for the dielectric constant. The dielectric constant calculating software gets the dielectric constant of the mixed liquid medium from the dielectric constant measuring apparatus. Then the dielectric constant calculating software gets the electrical length and the intrinsic impedance parameter which are required for the practical application environment from the keyboard. According to calculating and comparing, the proportion of the deionized water and the ethyl alcohol in the mixed solution is adjusted by controlling two programmed switches. Thus the online adjustment of electrical parameters is realized. In the invention, the online adjustment of the electrical parameters of the pulse forming line is realized. The problems of poor environmental adaptability, long lead time, high cost of production, etc., are solved.
