The invention relates to a three-power-supply-mode wheel tooth rail train power supply conversion circuit, a rail traffic system and a method, AC25kV or DC3000V power supply is received from an overhead contact line equipment through a train high-voltage circuit, the power supply is directly used for operation of a traction system after being distributed and converted, and meanwhile, the power supply is used for power storage of a storage battery; when the electric energy of the storage battery is sufficient, low-speed running electric energy can be provided for a train traction system without high-voltage electricity. Under the condition that the train has high-voltage power supply, the train runs through high-voltage power supply, and under the condition that the train does not have high-voltage power supply, the train runs through DC110V power supply. Operation requirements of the wheel tooth rail train under different line conditions are met, a power supply system does not need to unify a power supply mode, line power supply transformation cost is reduced, and power supply system construction time is shortened.

    本发明涉及三供电制式轮齿轨列车供电转换电路、轨道交通系统及方法,通过列车高压电路从接触网接收AC25kV或DC3000V的供电,将供电进行分配和转换后直接用于牵引系统运行,同时给蓄电池储电,当蓄电池电能充足时可以在没有高压电的情况下给列车牵引系统提供低速运行的电能。在列车有高压供电的情况下通过高压供电使列车运行,在列车没有高压供电的情况下通过DC110V供电使列车运行。本发明满足了轮齿轨列车在不同线路情况下的运行需要,无需供电系统统一供电制式,利于减少线路供电改造的成本,降低供电系统建设的时间。
