Solid state transformer with a LC filter for distribution network

The concept of solid state transformer (SST) has become one of most emerging and focused topic in 21 st century as mentioned by Massachusetts Institute of Technology (MIT) Technology review. With the increased in complexity and power demands we need to move towards new technology and SST is the only solution. If smart grid is the future of electrical power system then SST is the brain of this system. It would not only provide the efficient functioning as a conventional transformer but also provide other benefits, particularly on demand reactive power maintenance for the grid, good power quality, fault isolation and voltage conversion. In this paper, we are going to discuss the application and proposed topologies in distribution system.
