Disclosed are a train and a multi-current power conversion system thereof. The system comprises: a transformation module, an inductance module, a target switching tube, a first capacitance, a post-circuit, a target switching unit and a rectifier. The transformation module is used to, when receiving different alternating currents, output to the rectifier alternating currents having the same voltage; and to, when receiving direct currents, output to the inductance module direct currents. The inductance module is used to, when the transformation module receives the kth alternating current, conduct a first end to a second end thereof, and control the equivalent inductance between the first end and the second end to be the preset equivalent inductance corresponding to the kth alternating current. The rectifier is used to, when the transformation module receives different direct currents, control a switching device thereof to be on or off according to corresponding rules such that the voltage provided to the post-circuit remains the same. The solution of the present application supports at least 4 kinds of grid voltage systems.
