Solid state transformers: a critical review of projects with relevant prototypes and demonstrators 2023 Access copy available to the general public Unrestricted The ongoing energy transition has changed the architecture of electricity networks in ways that conventional power transformers are not able to cope with the new required functionalities. For this purpose, the solid state transformer (SST), which comprises state of the art power electronics with galvanic isolation to interconnect two separate alternating current (AC) or direct current (DC) power grids, is considered to be the dominant solution. The purpose of this paper is to provide a practical, application-oriented review of the SST. In this context, the main functionalities and possible applications of the SST are presented, including smart grids (SGs), data centres, railways, offshore wind farms, etc. Furthermore, the main developed SST prototypes are analysed with special focus on the related projects, demonstrators, stakeholders and rated values, e.g., voltage, switching frequency and power. The analysis is concluded with the future trends and challenges regarding the wider implementation of SST technology in the electrical grid. info:eu-repo/grantAgreement/EC/H2020/957769/EU/Towards Intelligent DC-based hybrid Grids Optimizing the network performance/TIGON This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 957769-TIGON info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.6 2023 COMPUTER SCIENCE, INFORMATION SYSTEMS 115 / 250 = 0.46 2023 Q2 T2 PHYSICS, APPLIED 81 / 179 = 0.453 2023 Q2 T2 ENGINEERING, ELECTRICAL & ELECTRONIC 157 / 353 = 0.445 2023 Q2 T2 0.644 2023 Electrical and Electronic Engineering 2023 Q2 Computer Networks and Communications 2023 Q2 Signal Processing 2023 Q2 Hardware and Architecture 2023 Q2 Control and Systems Engineering 2023 Q2 5.3 2023 info:eu-repo/semantics/review info:eu-repo/semantics/publishedVersion Fotopoulou, M.
