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

该SBIR第一阶段研究项目旨在证明利用新型纳米磁性浆料用于下一代小型化电子应用的DC-DC转换器的可行性。目前的DC-DC转换器是电子元件小型化的主要障碍，这是由于常规的微尺寸磁性材料只能在低频下有效地使用，而在高频（1 MHz）下，由于与常规的微尺寸磁性材料相关联的固有涡流损耗，存在显著的磁芯损耗。这一工作将促进对纳米磁学及其作为高频嵌入电感在电力电子中的应用的理解。这样的嵌入式电感器被期望具有高电感、低磁芯损耗，并且可以在低频下操作。所提出的技术的更广泛的影响是为急需的小型化电子和电信行业开发高效、小尺寸、超低损耗电感元件的可能性。所提出的磁性纳米复合材料浆料的预期益处/潜在商业应用将通过以非常低的损耗将电感器组件工作频率提升到超过400 MHz或更高来满足这种特定需求，从而实现器件小型化以及低温电子制造工艺。

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.
