This paper introduces a novel Cascaded H-Bridge (CHB) with Multi-Active-Bridge (MAB) based Solid-State-Transformer architecture that integrates Energy Storage Systems (ESS) to mitigate peak power demand caused by Electric Vehicle (EV) Fast-Charging-Stations (FCS) and enhance grid power quality. The proposed topology enables controlled power transfer between the grid, the FCS, and the ESS, incorporating an isolated five-port bidirectional DC-DC converter composed of five full-bridge cells and a multi-port five-winding medium-frequency transformer that reduces the number of components in the system, thereby improving efficiency and lowering system complexity. This paper discusses the architecture and analysis of the proposed topology and its different operating modes. The validation of its operating modes has been demonstrated through simulations and an experimental setup.
