SBIR Phase I: Nanomagnetic Paste for Miniaturized Ultrahigh Frequency DC-to-DC Converter

这个SBIR第一阶段的研究项目旨在证明开发一种新型纳米磁性浆料的可行性，该浆料可用于用于小型化电子应用的下一代超高dc - dc转换器。目前的dc - dc转换器是电子元件小型化的主要障碍，因为传统的微尺寸磁性材料只能在低频下有效使用，而在高频（1mhz）下，由于传统的微尺寸磁性材料固有的涡流损耗，存在显着的磁芯损耗。这项工作将促进对纳米磁性及其在电力电子中作为超高频嵌入式电感的应用的理解。这种嵌入式电感有望具有高电感，低铁芯损耗，并能在超高频下工作。提出的技术的更广泛的影响是开发高效，小尺寸，超低损耗的电感元件的可能性，为迫切需要的微型化电子和电信行业。所提出的磁性纳米复合浆料的预期效益/潜在商业应用将通过将电感元件的工作频率提高到超过400 MHz或更高而具有非常低的损耗，实现器件小型化以及低温电子制造工艺来满足这一特殊需求。

This SBIR Phase I research project aims to demonstrate the feasibility of exploiting a novel nanomagnetic paste for the next generation of ultrahigh DC-to-DC converters for miniaturized electronic applications. Current DC-to-DC converters are the major impediment for miniaturization of electronic components, due to conventional microsized magnetic materials can only be used effectively at low frequencies, while at high frequencies (1 MHz) there is a significant core loss due to the intrinsic eddy current loss associated with conventional microsized magnetic materials. This work will promote the understanding of nanomagnetics and their applications as ultrahigh frequency embedded inductors in power electronics. Such embedded inductors are expected to possess high inductance, low core loss, and can be operated at ultrahigh frequencies. The broader impact of the proposed technology is the possibility of developing highly efficient, small size, ultralow loss inductive components for critically needed miniaturized electronics and the telecommunication industry. The anticipated benefits/ potential commercial applications of the proposed magnetic nanocomposite paste will meet this particular need by promoting inductor component working frequency to over 400 MHz or higher with very low losses, enabling device miniaturization as well as low temperature electronic fabrication processes.
