摘　　要：针对高速铁路可变编组动车组电力牵引系统问题,提出了一种模块化牵引单元实现方案。采用级联H桥与DC/DC结合的方法,实现了电力牵引动力灵活配置,大大降低牵引传动单元的体积与质量,同时具有一定的冗余性。Simulink仿真验证了方案的可行性和有效性。A scheme for realizing modular traction units was proposed with respect to the electric power traction system used for variable marshalling CRH(China railway high-speed)trains.According to this scheme,the cascaded H-bridge and DC/DC were combined to realize flexible configuration of electric traction power,thus greatly reducing the volume and weight of the traction drive unit in addition to certain redundancy.Simulink simulation verified the feasibility and effectiveness of the proposed scheme.
