Developments in d.c. traction power supply rectifiers
International Conference on Developments in Mass Transit Systems, 1998Rectifier theory and its application to diode-type power convertors to provide DC power supplies for urban electrified railway systems has long been established and used successfully throughout the world. Traditionally, limitations in diode power ratings lead to large numbers of diodes being required in the rectifier which resulted in the fused design ...

Electric power characteristics of all-parallel AT traction power supply system
Proceedings 2011 International Conference on Transportation, Mechanical, and Electrical Engineering (TMEE), 2011All-parallel autotransformer (AT) traction power supply system is widely applied to China high-speed railways. The traction feeding network of this kind is more complicated than traditional AT networks. It contains more current loops and the current distribution become more complex.

Power Analysis on DCAT Traction Power Supply System for DC Railways
2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018For DC railways, DC auto-transformer (DCAT) traction power supply system may solve the rail potential and stray current and issues fundamentally. However, the load power may reach to millions of watts, and the starting current of trains may reach to thousands of amperes, which may lead to the high cost and volume of DCAT system.
