Abstract
As a crucial component in modern flexible DC distribution systems, solid-state transformers (SSTs) offer high efficiency, high stability, and strong adaptability. With the growing demand for high-performance and intelligent equipment in today's power systems, SSTs are increasingly becoming a key technology to overcome the limitations of conventional power equipment. This paper discusses key technological breakthroughs of SSTs in flexible DC distribution systems, including advancements in control strategies, power density, thermal management, and system reliability. Through an in-depth analysis of SST technology, this paper elucidates its potential in future power networks, particularly its significance in smart grids and renewable energy integration. With optimized design and technological innovation, SSTs will provide more efficient and flexible solutions for modern distribution systems.
Key words： Solid-state transformer; Flexible DC distribution; Technological breakthrough; Power density; Smart grid
