Low-Cost Compact Medium Voltage Connected DC Charging Infrastructure
This project is a collaboration between NC State, North Carolina State University (NCSU) and a major US Electric Utility.
This project aims to develop an economical, compact medium voltage connected Direct Current (DC) charging infrastructure for Electric Vehicles (EVs). The Solid-State Transformer (SST) architecture will enable a Megawatt (MW)-level Fast Charger, reducing capital cost. The proposed topologies will be evaluated for efficiency, reliability, and power density. In addition, a real-time controller hardware-in-the-loop will be used to validate the concept, and the integration of Photo-Voltaic (PV) cells and Battery Energy Storage System (BESS) must adhere to IEEE1547-2018. This collaborative project is between NC State and a major US Electric Utility.

Low-Cost Compact Medium Voltage Connected DC Charging Infrastructure
The goal of this project is to develop Solid-State Transformer (SST) architectures for Megawatt (MW)-level Electric Vehicle (EV) Fast Charger, emphasizing reduced capital cost. We will also investigate the benefits of the possible topologies in terms of efficiency, reliability, power density. A real-time controller hardware-in-the-loop will be used to validate the proposed concept. The expected integration of Photo-Voltaic (PV) cells and Battery Energy Storage System (BESS) require the implementation conforming to IEEE1547-2018.
