陆军对未来战斗系统（FCS）陆军技术目标（ATO）计划的脉搏力量正在开发高压脉冲功率组件，以允许在地面战车中整合革命性的生存能力和致命性。本文将描述高能密度（红色）双轴导向的聚丙烯（BOPP）电容器的最新进展。通过使用高能量密度薄膜电容器来实现许多脉冲功率负载的中间能量储能，目前利用BOPP作为首选的介电膜。在过去的十年中，HED BOPP电容器的最新进展导致能量密度从1990年代初的相似之处增加到0.5 j/cc的一倍以上，达到2003 - 2004年的时间段的1.2 J/cc，同时仍然具有合理的直流电流（ DC）生命和开枪。进一步的研究导致了HED电容器，其能量密度为2.0 j/cc的射击时，并执行寿命水平，这是候选镜头数量并不重要的应用。正在追求通过SAIC和Advance Capacor Inc/ICAR（ACI/ICAR）进行的当前研发工作，目的是开发> 1.8 J/CC的目标，同时保持合理的DO和开枪命中寿命。此外，也正在进行努力，以开发出非常长的DC寿命HED电容器。
The Army's Pulse Power For Future Combat System (FCS) Army Technology Objective (ATO) program is developing the high-voltage pulse power components required to allow for the integration of revolutionary survivability and lethality in ground combat vehicles. This paper will describe recent advances in high energy density (RED) biaxially-oriented poly-propylene (BOPP) capacitors. Intermediate energy storage for many pulse power loads is achieved through the use of high energy-density thin-film capacitors, currently utilizing BOPP as the dielectric film of choice. Recent advances in HED BOPP capacitors over the last decade have resulted in the energy density more than doubling from similar to 0.5 J/cc in the early 1990s to similar to 1.2 J/cc in the 2003-2004 timeframe while still possessing reasonable direct current (dc) life and shot life. Further research has resulted in HED capacitors with energy densities of 2.0 J/cc at reduced shot and do life levels which are candidates for applications in which the number of shots are not critical to the application. Current research and development efforts through SAIC and Advance Capacitor Inc/ICAR (ACI/ICAR) are being pursued with the goal of developing > 1.8 J/cc while maintaining reasonable do and shot life. In addition, efforts are also' ongoing to develop exceptionally long dc-life HED capacitors.
