A bidirectional DC/DC converter, an urban rail vehicle and a traction system thereof. The bidirectional DC/DC converter comprises a DC/DC module, a control module, a chopping inductance module and a bypass contactor. By means of the control module and according to the output voltage of a power supply module, the DC/DC module is selected to work or the bypass contactor is closed to complete electric energy transmission, and there is no need to re-design an original traction system, thereby saving on costs; at the same time, the DC/DC module uses multiple multi-phase staggered parallel circuit structures, such that the output power of the bidirectional DC/DC converter is improved, the buck-boost range is large, and the requirements of the traction system of the urban rail vehicle can be met; in addition, multiple phases share one control module, so that the size of the bidirectional DC/DC converter is further reduced, and the costs are saved on.
