Abstract: Employing the three-level neutral point clamped (3L-NPC) topology for the LLC resonant DC-DC converter and utilizing the integrated gate commutated thyristor (IGCT) has enabled realization ...
A transformer protection relay does not replace upstream devices. It defines responsibility. By clearly assigning fault ...
Abstract: The transformer inrush current has been a potential threat in wind farm connected modular multilevel converter based high-voltage direct current (WF-MMC-HVDC) system due to the low ...
