Summary:High-altitude operational environments pose new challenges to the reliability of rail transit equipment. To meet the through traffic requirements connecting the Lasa-Rikaze and Lasa-Linzhi railways, which involve both electrified and non-electrified operations, China has successfully developed a dual-source power-centralized EDMU for plateau railways. This paper briefly describes the parameters and performance requirements of this EDMU diesel-power car, highlighting higher requirements in terms of miniaturization and lightweight of complete cars, along with more demanding requirements for the traction performance of the electric drive system. The paper elaborates on the main circuit and key technical parameters of the electric drive system for the diesel power car of this EDMU, analyzing the technical characteristics of the AC drive system, featuring the integration of traction, auxiliaries, and head-end power. It summarizes the type tests and passenger transport services conducted on EDMUs equipped with this
