Abstract
Power Electronic Transformer (PET) technology is one of the future technologies for high power conversion drives. Over the past years, various research and studies are conducted to explore the technical challenges for high-speed rails. The traditional locomotive transformer experience from a massive weight with poor efficiency. Thus power electronic transformers (PETs) is one of the promising solutions in the field of rolling stock with greater advantage of the reduction in size and weight of the locomotive transformer. This paper aims to describe high-frequency transformer merged DC to DC power converter feeding to a traction converter coupled traction motor is utilized in electric locomotives. This paper also suggests a dual phase algorithm method for the reduction of higher order harmonics during power conversion stages. The IGBT based dc to dc converter with traction converter for power electronic transformer has been verified by the simulation results with MATLAB/SIMULINK.
