Abstract

Transferring bulk power via high voltage direct current (HVDC) transmission is dominated by linecommutated converters (LCC). This is due to the robustness and higher ratings of the thyristors as wellas the higher converter efficiency. Nevertheless, most of these transmission networks are point to point.This is due to the challenges of allowing multi-terminal LCC based networks and power reversal. Thispaper introduces a new dc-dc converter topology that allows connecting two independent LCC networks.The proposed converter is based on insulated gate commutated thyristors (IGCTs). Utilizing IGCTsallow mimicking similar control and performance as in insulated gate bipolar transistor (IGBT) basedvoltage source dc-dc converters. However, IGCTs have more superior features over IGBTs such ashigher efficiency, higher short circuit current and higher power ratings. Detailed analysis andsimulations are provided to validate the proposed converter topology, which confirms its potential inconnecting HVDC-LCC networks.
