Solid State Transformer with Integrated Input Stage [PDF]
2019 IEEE International Conference on Industrial Technology (ICIT), 2019 In this paper, a solid state transformer (SST) with integrated stages is addressed. The SST has been originally proposed for traction applications, after as an option to face the new requirements of the distributed generation but also suggested in many applications. There are different topologies, from one to three stages; certainly each one with their
