Voltage transient management for Alternating Current trains with vacuum circuit breakers
IET Electrical Systems in Transportation, 2022 Alternating current power supplies and rolling stock with 25 kV (50 or 60 Hz) and 15 kV (16.7 Hz) traction systems do not have the characteristics and behaviour of a typical three‐phase medium‐voltage distribution system. Switching inductive loads with a

Feasibility of applying inductive filtering technology to the HVDC transmission system
The Journal of Engineering, 2018 This study explores the feasibility of applying inductive filtering technology to high-voltage direct-current (HVDC) transmission system since only filtering in the net side may lead to a lot of harmonics in the converter transformer. Basic principles of

Influence of transformer leakage inductance on DC high current generator
Journal of Physics: Conference Series, 2022 Abstract The efficiency is affected by the parameters of components in the DC high current generator. The leakage inductance of the rectifier transformer will affect the output and filtering effect of the device and reduce the power quality of the public network. To improve the output and filtering effect of the DC high current generator,
