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.

    本发明提供一种同相供电装置,包括单相分裂多绕组变压器和三组变流模块,所述单相分裂多绕组变压器包括单相原边绕组和多个单相副边绕组,每组变流模块包括n个背靠背H桥单元,每组变流模块中的n个背靠背H桥单元的整流侧端口级联,每个背靠背H桥单元的牵引侧端口分别与所述单相分裂多绕组变压器的单相副边绕组对应连接,其中,三组变流模块级联后的整流侧端口采用Y形连接或△形连接并作为所述同相供电装置的三相输入端,所述单相分裂多绕组变压器的单相原边绕组作为所述同相供电装置的单相输出端,其中,n≥1。本发明能实现铁路全线同相供电贯通而无需分相,保证机车的高速、重载运行。
