摘要

在电容型储能脉冲功率电源中

脉冲电容器的储能密度直接影响脉冲功率电源和脉冲功率系统的小型化发展。目前

脉冲电容器的介质材料多采用双向拉伸聚丙烯薄膜（BOPP）

其储能密度很难进一步提升

因此需要研究新型电容储能材料

以提高电容器的储能密度。本文以电容器用储能电介质为研究对象

对聚合物基无机纳米复合电介质（PVDF/TiO2）、聚合物基全有机复合电介质（PVDF/PP）和高偶极矩无定形聚合物（ArPU）3种新型储能电介质的电性能参数作了对比。此外

测试并绘制了他们的D～E曲线

并以BOPP为参考

对他们的放电效率进行了研究。测试结果表明

这3种新型储能电介质的放电效率均随频率的升高而升高。

Abstract

In the capacitive energy storage pulse power supply

the energy storage density of the pulse capacitor directly affects the miniaturization development of the pulse power supply and the pulse power system. At present

the dielectric material of pulse capacitors mostly adopts biaxially oriented polypropylene film（BOPP）and its energy storage density is difficult to be improved further. It is therefore necessary to study a new type of capacitor energy storage material to improve the energy storage density of the capacitor.In this paper

the energy storage dielectrics for capacitors are taken as the study object. The electrical performance parameters of such three new energy storage dielectrics as polymer-based inorganic nanocomposite dielectrics（PVDF/TiO2）

polymer-based all-organic composite dielectrics（PVDF/PP）and high dipole moment amorphous polymers（ArPU）are compared. Moreover

their DE curves are tested and plotted and their discharge efficiency is studied with BOPP as reference. It is shown by the test result that the discharge efficiency of the three new energy storage dielectrics increase with the increase of frequency.
