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
