The Generating Mechanism and Suppression Measure of the ‘Wheel‐Rail’ Rolling Arc for Electrified Trains

open access: yesHigh Voltage, Volume 11, Issue 2, Page 370-384, April 2026.
ABSTRACT As the ‘main blood vessel’ of the traction power supply system for high‐speed trains, the ‘wheel‐rail’ coupling grounding reflux system provides the vital channel to send traction current back to terrestrial substations; meanwhile, the rail track also plays a role in transmitting the train's occupancy signal to the control system. An insulated

An Open Access Database of Power Diode Characteristics at Cryogenic Temperature

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
The development of power electronic converters operating at cryogenic temperatures is limited by the lack of data on electronic components outside the standard temperature range specified by manufacturers (typically above −65°C, i.e., 208 K). To fill this gap, the construction of an open access database of power electronic component characteristics at ...

A Novel Negative‐Sequence Compensation Method for Electrified Railway Traction Power Supply Systems Based on Dual Rotary Phase Shifting Transformers

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This article proposes a novel electromagnetic rotary negative‐sequence compensator based on dual rotary phase‐shifting transformers to mitigate negative‐sequence currents in single‐phase traction power supply systems. The topology, mathematical model and coordinated speed control strategy are established, with sequence characteristics analysis ...

Modeling and Control of Rail Potential With Partial Backflow Obstruction in DC Metro Systems

open access: yesIET Electrical Systems in Transportation, Volume 2026, Issue 1, 2026.
Running rails are employed as the reflux conductor in DC metro systems, whose longitudinal resistance and joint resistance usually increase with the operating years of the system. Subsequently, the partial backflow obstruction occurs, which will greatly increase rail potential (RP) and endanger the security of the metro line operation. In this paper, a

Emergency Power Sharing by Using a Self‐Traction System in a Mass Rapid Transit Railway

open access: yesIET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.
ABSTRACT Systemwide traction power outages in mass rapid transit systems (MRTSs) can cause trains to stop between stations, leading to service disruption and urgent passenger evacuation requirements. Onboard emergency self‐traction systems (ESTSs) can mitigate this risk by enabling a stranded train to reach the nearest station at low speed.
