项目摘要

The broader impact/commercial potential of this project is to a wide range of electronics in the areas of communications, Internet, portable electronics, and power electronics. Although magnetic based transformers have been the industry standard for over a century they have many negatives including miniaturization difficulties, electromagnetic interference issues, and issues with larger voltage step-up applications. The main goal of the research is to develop a ceramic replacement for magnetic transformers that is both conducive to miniaturization, provides higher power densities, provides a large increase in safe operating temperatures, and that is cost competitive with standard magnetic devices. This technology will provide important advantages for many applications; the ability to produce at low cost also opens up large new markets that are not easily reached using conventional magnetics.This Small Business Technology Transfer (STTR) Phase 2 project aims to develop new low temperature sintering processes and transformer structures that enable the use of base metal electrodes to replace very expensive platinum. This drastically reduces costs of ceramic transformers and substantially improves performance due to the fact that a poor electrical/thermal conductor, Platinum, is now replaced with base metal (Copper) that is a high performance electrical/thermal conductor. This translates into both higher power throughput in devices that are lighter weight and lower profile and also a new ability to now match the high temperature range of wide bandgap power devices. The success of this program immediately leads to a revolutionary next step of being able to insert power management/conversion electronics directly within integrated circuits such as in application specific integrated circuits (ASIC) and field programmable gate arrays (FPGA).

该项目的更广泛的影响/商业潜力是通信，互联网，便携式电子和电力电子产品领域的广泛电子产品。尽管基于磁性的变压器已成为一个多世纪以来的行业标准，但它们具有许多负面影响，包括小型化困难，电磁干扰问题以及较大的电压加速应用问题。该研究的主要目的是开发用于磁性变压器的陶瓷替代品，既有利于微型化，都提供更高的功率密度，可提供安全的安全工作温度的大幅度提高，并且与标准磁性设备具有成本竞争力。该技术将为许多应用提供重要的优势；低成本生产的能力还打开了不容易使用常规磁化物来达到的大型新市场。这款小型企业技术转移（STTR）第2阶段项目旨在开发新的低温烧结过程和变压器结构，以实现使用碱金属电极以更换非常昂贵的铂金。这大大降低了陶瓷变压器的成本，并且由于较差的电气/热导体Platinum现在被倒金属（铜）代替，这是高性能电气/热导体。这转化为重量较轻和较低的设备中的更高功率吞吐量，并且现在可以匹配宽带盖板电源设备的高温范围的新功能。该程序的成功立即导致革命性的下一步，能够直接在集成电路中插入电源管理/转换电子设备，例如在应用程序特定的集成电路（ASIC）（ASIC）和现场可编程门阵列（FPGA）。
