Serious power quality and neutral sections disadvantage restrict the evolution of traditional traction power supply system. An advanced co-phase traction power supply system is proposed in this paper based on three-phase to single-phase converter as the key equipment in substation. This converter adopts multi-module diode clamped multi-level algorithm, connects between industrial grid and feeder line without using output transformer. It transfers active power from three-phase grid isolated to one-phase traction line, and provides the frequency, phase and amplitude controlled output voltage. Then, the feeder line between different substation can be connected directly, and constructs an ideal co-phase traction supply system in the same phase. The performance of the converter is validated by the discussion and simulation results in this paper.
