The magnetics of power electronics has particular potential for improvement, as these components are typically the largest and volumétrica I ly inefficient in a power circuit. Nowadays, the trend is to develop multiscale multiphysics structures to yield peiformance characteristics favorable in power electronic devices and power converters' applications. As tire dimensions of materials are reduced to the nanometer realm, they often exhibit novel and interesting behavior, which constitute the basis for a new generation of electronic devices. Nanoparticles physical and chemical properties behavior is unique and peculiar compared to conventional or classical materials, for instance, silicon is a semiconductor wiiile silicon nanowire is a good conductor. Hence, the exploitation and exploration of nanotechnology is critical to achieving reliable nanometer-based power devices with small footprint and reduced power consumption, among others. Nanotechnology-based power inductor that utilizes hundledmultiwalled carbon nanotubes and thin magnetic plates as cores can provide higii-powerdensity, low-power-loss, and high performance in a small size for system on-chip (SoC). The bundled-multiwalled carbon nanotubes based power inductor with single-layer and three turns occupies an area of 0.1225 mm^ exhibits an inductance of 263 nH, a quality factor of 771 at 20MHz, and a dc rated current of 200 inA. The fabrication, design, analysis, multiscale multiphysics modeling, and simulation results oftiie bundled-multiwalled carbon nanotubes based power inductor are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
