There are basically three components in experimental installation of a high voltage supplier , a capillary tube with a pipette or needle of small diameter and a metal collecting screen 电纺丝技术的基本装置由高压直流电源、带有细小喷丝头的样品管和收集板三部分组成。
High - voltage dc ( hvdc ) power system , which has the advantages such as light weight and easiness to realizes uninterrupted power supply , has been attracted more and more attentions 高压直流电源系统具有电网重量轻、易实现不中断供电等特点，有着良好的应用前景，近年来成为研究的热点。
A great deal of research work has been done in this domain in foreign , and there have been plentiful productions . as well , there is much research work in progress in some domestic research institutions , in this domain , especially due to requests of national defense construction . it is for requests of national defense construction that an research institution establishes a special item to research high - voltage high - power converter in a domestic research institution , considering especial requests that the space - flight and aviation systems make for high - voltage dc - dc powers 高效、高功率密度、高压大功率直流变换技术属于电力电子学范畴，国外已在此领域开展了大量的研究工作，并取得许多成果。国内也有一些单位从事该领域研究，特别是针对国防建设的需要。本项目正是某研究单位国防建设的需要，考虑到在航空航天领域对高压直流电源的特殊要求，设立了专门研究项目，展开对高压大功率直流变换技术的研究。
