The invention provides an in-phase power supply device. The device comprises a single-phase split multi-winding transformer and three groups of converter modules, the single-phase split multi-windingtransformer comprises a single-phase primary winding and a plurality of single-phase secondary windings, each group of converter modules comprises n back-to-back H-bridge units; rectification side ports of the n back-to-back H-bridge units in each group of converter modules are cascaded; a traction side port of each back-to-back H-bridge unit is correspondingly connected with a single-phase secondary winding of the single-phase split multi-winding transformer, wherein rectification side ports after the three groups of converter modules are cascaded are connected in a Y shape or a Y shape and are used as three-phase input ends of the in-phase power supply device, a single-phase primary winding of the single-phase split multi-winding transformer is used as a single-phase output end of the in-phase power supply device, and n is greater than or equal to 1. According to the invention, railway whole-line in-phase power supply connection can be realized without phase splitting, and high-speedand heavy-load operation of the locomotive is ensured.
