Modelling, Control System Design and Comparison of Star and Delta Connected Solid-State Transformers: A study of three MVAC to LVDC Modular Multilevel Converter based Solid State Transformers for Ultra-Fast EV Charging Applications

With an increase in higher power (ultra) fast EV charging stations and a new EU law for mandatory deployments of EV charging stations, an optimal MVAC grid connection for these charging stations is desired. Considering this connection, the use of a solid-state transformer (SST) performs better in terms of weight, size and efficiency with a...
