Solid state transformers (SSTs) feature a series of functional advantages, such as voltage level conversion, electrical isolation, power regulation and control, multiple ac and dc ports, power quality control, and communications with other intelligent devices. In recent years, smart SST, also called as smart transformer (ST), has been developed based on the integration with advanced information technology. Smart SST has good application prospects in ac/dc hybrid distribution networks and microgrids for renewable energy integration, electric vehicle charging stations, data centers, rail, and other fields.
