초록

This paper presents a balanced 3/1 supply scheme for electric railway. By employing an active filter, the current of the three-phrase delivery system is balanced while the load is single phrase, which makes it possible for the traction system to behave like a pure-resistance load, with unity power factor and no harmonics. Simulation results are present to verify the scheme's topology and control strategies.
