Abstract: This paper includes a better topology of solid-state transformer (SST). In the process of designing the Ac to DC, DC to AC and Ac to AC conversions have been united in order to achieve greater efficiency. To get good and better efficiency from various SST, the AC to AC converters are being united in one matrix converter for better output performance. The newly proposed solid state transformer performs critical functions and has many more advantages such as correction in power factor, sag and swell elimination, flicker of voltage reduction and safe capability in order of error situations. Now additionally, it has includes many other benefits also such as low weight, minimum volume and reduction of dangerous liquid dielectrics includes just because it involves medium frequency transformer. The working and some actions of the newly proposed SST have been tested by the results via simulations.
