| Abstract: | With respect to the frequent converter module failures after CRH1 high-speed trains allocated in Fuzhou EMU （Electrical Multiple Unit） maintenance depot, corresponding failure analysis and strategy study were performed. Based on the control principle of middle direct current （DC） section, combined with the running and failure data of EMU as the problem occurred, real failure cause was distinguished through data comparison and instance validation, failure treatment and preventive measure were also proposed. |
