| 520 | |a As the concern for climate change increases, methods to reduce greenhouse gas emissions have become a priority. The transportation sector has been identified as a major source of greenhouse gas emission and is therefore a target for improvement. Specifically, vendors have promised to replace conventional internal combustion engine vehicles (ICEs) with battery electric vehicles (BEVs/EVs) or fuel cell electric vehicles (FCEVs) in the coming decades. Such a massive paradigm shift places significant demand on the electrical grid as alternatives like hydrogen pumps and EV chargers continue to replace existing gas stations.As the demands of systems such as power-to-hydrogen (P2H) and extreme fast charging (XFC) increase, there is a need for highly efficient, customizable, and scalable grid-tied power electronics that can be deployed rapidly. Conventional architectures that utilize line frequency transformers and low frequency buses pose many issues when it comes to efficiency, scalability, lead times, and cost. This thesis presents a bidirectional converter architecture comprised of stackable three-phase ac/dc converter modules, scalable to high-power and high-current applications. Multiple converter modules containing a converter power stage and controls can be stacked to obtain a medium-voltage ac (MVAC) tied system without the need for a line frequency transformer. The modular system architecture is made possible by a quadruple active bridge (QAB) dc/dc converter that provides isolation between each of the three ac-side phases within each module and the dc load. The system also removes the need for bulk energy storage by taking advantage of constant balanced three-phase power flow. Decentralized module-level controllers are also implemented to allow for system modularity and scalability. The proposed architecture is validated by simulations of a P2H system consisting of 18 modules and a scaled proof-of-concept hardware prototype consisting of two modules. | ||
