Analysis on radiated EMI of Solid-state transformer for a train

In this paper, before manufacturing a solid stale transformer mounted in the propulsion system of an electrie railway vehicle, modeling using a finite element analysis (FEA) program is used to predict the EMI generated in the solid state transformer system in advance. The EMI shielding performance of the transformer enclosure was analyzed. This was compared with the international F.MI standard for electric railway systems to determine whether the solid state transformer system can meet the EMI standard.
