SBIR Phase I: Cost Competitive High Temperature Film Capacitors with Three-Phase Nanocomposites

这个小企业创新研究（SBIR）第一阶段项目将开发和商业化具有高能量密度、高功率密度和高热稳定性的先进薄膜电容器。目前在许多中大功率系统中使用的直流母线电容器主要是60多年前发展起来的聚丙烯薄膜电容器，其热稳定性较低。该项目将使用专有的三相纳米介电成分开发原型电容器，该成分具有高热稳定性，高介电常数，低介电损耗以及低成本。该项目的更广泛的影响/商业潜力是开发具有成本竞争力的先进静电电容器，这些电容器是许多脉冲功率和电力电子设备的关键部件。这些先进的电容器将能够最大限度地减少电容器的尺寸和重量，并降低混合动力和插电式电动汽车、智能电网、石油/天然气/地热井下钻井和勘探、风力涡轮机发电机、并网光伏以及许多其他能源和军事系统中的电源逆变器的材料和维护成本。该项目的成功将促进先进开关技术的广泛采用，可节省30%的电能损失。

This Small Business Innovation Research (SBIR) Phase I project will develop and commercialize advanced film capacitors with high energy density, high power density, and high thermal stability. Current dc bus capacitors in many medium and high power systems are dominated by polypropylene (PP) film capacitors which were developed more than 60 years ago and they have low thermal stability. This project will develop prototype capacitors using proprietary three-phase nanodielectric compositions combining high thermal stability, high dielectric constant, low dielectric loss, as well as low cost. The broader impact/commercial potential of this project is development of cost-competitive advanced electrostatic capacitors that are critical components in many pulsed power and power electronics. These advanced capacitors will be able to minimize the capacitor size, weight and reduce the material and maintenance cost of power inverters in hybrid and plug-in electric vehicles, smart grid, oil/gas/geothermal down-hole drilling and exploration, wind turbine generators, grid-tied photovoltaic, and many other energy and military systems. The success of this project will facilitate the broad adoption of advanced switch technologies which can save the electricity energy loss by 30%.
