Abstract :
Power electronic transformer(PET) has been the focus of interest in recent years. Compared with conventional low frequency transformers, PETs can offer many additional functions such as phase shifting, frequency shifting and reactive power/harmonic compensation. This paper proposes a single phase PET for the Scott railway power system. The PET achieves active power control which balances the Scott´s secondary currents. The PET also achieves reactive/harmonic compensation. The configuration and control strategy of the proposed PET is discussed. Simulation results from PLECS verifies the effectiveness of the proposed PET and its control strategy.
