Project runs from 08/01/2018 to 01/31/2020
We propose a next generation high-performance isolated medium-voltage (MV) building block for electric vehicle (EV) dc ultra-fast charging and other MV rectification applications. This work builds on the efforts to develop a solid-state transformer as a part of the NSF FREEDM Engineering Research Center. The main innovation is in the design of the high-performance isolated single-stage converter that combines a power factor correction and an isolated dc/dc conversion stage. The motivation for this work is to more efficiently serve the growing demand for dc fast and ultra-fast recharging infrastructure for EVs by significantly reducing the recharging time and bringing a gas station-like experience to the EV users. Coming from Future Renewable Electric Energy Distribution and Management (FREEDM) Systems Center (an NSF-funded generation-III Engineering Research Center), the team will build on their previous experience in MV systems to develop a 35 kW MV EV fast charger building block using this unique technology. The team aims to transfer the developed technology to the marketplace by employing market research and customer discovery strategies learned in the first Cohort of the newly formed NCSU NSF I-CorpsTM Site.
