Review demonstrates foundational concepts and structural evolution in solid-state transformers, highlighting persistent challenges in protection, isolation, and reliability.

Key Points

To review the historical origins, technological evolution, and foundational circuit topologies underlying modern solid-state transformers compared to conventional low-frequency counterparts.
Conducted a technological and historical review of solid-state transformer (SST) patents, concepts, and topologies dating back to the 1960s.
Analyzed structural similarities across modern SST topologies, evaluating their operational mechanisms, isolation stages, and grid integration capabilities.
Identified that modern SST architectures derive from a combination of a few foundational concepts first introduced or patented in the 1960s, specifically medium-frequency isolation stages, medium-voltage interfacing, and controllability.
Determined that SSTs provide substantial reductions in weight and volume alongside efficiency and controllability gains over low-frequency transformers in traction and smart grid applications.
Established that critical technical barriers persist in system protection, high-voltage isolation, and hardware reliability.
