Abstract：This paper presents a balanced 3/1 supply scheme for electrified railway. By employing an active filter, the current of the three-phase power delivery system is balanced while the load is in single phase, which makes it possible for the traction system to behave like a three-phase balanced pure-resistance load to the power delivery system, with unity power factor and no harmonics. Simulation results are presented to verify the scheme′s topology and control regularity.
Keywords：active filter electrified railway power supply system three phase single phase
