Abstract—As the “brain” of the modern photovoltaic power systems, DC solid-state transformers (SSTs) are playing an increasing important role in integrating different PV modules, batteries, and supercapacitors. This paper aims at improving the conversion efficiency of DC SST for a wide operating. In this study, the advanced topologies of a DC–DC converter for applications involving the harvesting of solar energy are discussed. Several. Driven by the global energy transition, the rapid expansion of photovoltaic (PV) capacity—particularly in China's “sand-Gobi-desert” mega-bases—demands highly efficient collection technologies. DC collection, offering low losses, compactness, and high reliability, is emerging as a critical solution.
