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.parisnaturalfoodes.shop/product-category/soap-3-in-1-for-kid-tropical-coconut/
