Rating: 

5

This paper deals with the use of multiport power electronic transformer (PET) with multi winding medium frequency transformer (MW-MFT) for traction systems where in which single-phase line frequency medium voltage is converted into multiple medium frequency voltages. This system is proposed in order to reduce the size and cost of using the transformer in electric traction applications. The high frequency multiport PET can be used in locomotives, electric multiple units (EMU), marine propulsion, grid applications. This topology consist of multiple active bridge (MAB) circuits which act as isolation units. Voltage balancing control of DC source are described. Simulation results are presented to verify the performance of the proposed system.
