Their large size is, however, a major bottleneck for power module integration and efficient power management. High-density and miniaturized inductors can help migrate the power converters close to the processor. This can lead to lower losses, more efficient and granular power delivery. However, traditional magnetic materials that are used to fabricate inductors cannot achieve very high power densities or current-handling. Magnetic flake-composite materials provide unique opportunities to address these challenges by enhancing permeability, reducing core losses, miniaturizing\u0026nbsp;\u0026nbsp; and integrating inductors close to the processor load.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe primary objective of this research is to model, design and demonstrate high-performance power inductors with high inductance densities, low DC resistance, and high current-handling. This requires major advances in magnetic materials with high permeabilities and high-frequency stability as well as specific inductor designs, materials, and\u0026nbsp; innovative substrate-embedding processes and characterizations.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003ETwo-dimensional magnetic flakes provide multiple degrees of freedom to achieve high in-plane permeability with large X-Y dimensions and low eddy current losses from small Z dimensions. By synthesizing them as polymer composites, adequate thickness can be achieved for high current-handling. Advanced materials with 2D magnetic flakes will be designed to achieve high in-plane permeability, low losses from their plate-like morphology and high field-anisotropy. These materials are processed to achieve adequate thicknesses for current-handling. Such advanced materials are then integrated into inductors with innovative designs for achieving high inductance density with low DC resistance and high current-handling, with smaller footprints and lower thicknesses. Innovative material processing is developed to integrate such inductors with ultra-high performance into thin substrates.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"\u0022Modeling, Design, Fabrication and Characterization of High-Density Inductors with Advanced Magnetic Composites"}],"uid":"27707","created_gmt":"2018-11-26 17:34:35","changed_gmt":"2018-11-26 17:34:35","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2018-12-04T10:00:00-05:00","event_time_end":"2018-12-04T12:00:00-05:00","event_time_end_last":"2018-12-04T12:00:00-05:00","gmt_time_start":"2018-12-04 15:00:00","gmt_time_end":"2018-12-04 17:00:00","gmt_time_end_last":"2018-12-04 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
