Abstract
Solid-state transformer (SST)-based ultra-fast charging stations (UFCSs) are emerging as a key technology in next-generation electric vehicle (EV) infrastructure, addressing the growing demand for efficient charging. Unlike traditional line-frequency transformers, SSTs offer higher energy conversion efficiency, smaller size, and better scalability. However, challenges such as control complexity and grid stability remain. This review analyzes existing SST topologies (both classical and new) and control methods, discussing their impact on system performance, and finally, it provides an outlook on future technological trends.Description
