Comprehensive Review of Solid State Transformers in the Distribution System: From High Voltage Power Components to the Field Application

This paper presents a systematical and progressive appraisal of the technology since inception AC-AC conversion, which is seen to be an indispensable vital for advancement Solid State Transformer (SST) in distribution system. Special attention given concepts/topologies architecture SST, DC-DC conversion devices isolation facet, inversion gadget bridge arrangement their integration development economically viable efficient SST design. For purpose this article, number research papers, proposals dissertations/studies have been accessed that mostly cover work related device brief discussions about several aspects. The various sections article are correspondingly devoted review design its configurations, significant stages converter from transformer-specific perspective lastly high-frequency inverter. In critical appraisal, three-stage perspective, dual half-bridge inverter most promising means, offering tremendous advantages over other configurations with emphasis on economy, high flexibility control performance; thereby weighed as workable, practical realistic solutions. foremost potential application expedient includes component power grid.
