This paper provides an overview of an early attempt at developing a simulation model on a solid-state transformer (SST) based on input-serial and output-parallel (ISOP) topology. The proposed SST is designed as a base for a smart grid (SG). The paper provides a theoretical review of the power converters under consideration. as well as their control techniques. https://www.spidertattooz.com/CND-Shellac-Be-Demure-0-5oz-p13568/
