Abstract

This paper studies a DC/DC converter based on IGBT-bridges which is suitable for connection to HVDC (High Voltage DC) and for building high power DC grids. The DC faults are of highest concern for DC grids, and the primary converter design aims are to achieve inherent current regulation under DC faults in addition to minimizing converter losses. Design studies show that a range of converter parameters exist which will give fault DC current magnitudes close to rated currents. It is shown that it is possible to have controllable operation even for worst case DC faults at either of the DC terminals. The results are confirmed using detailed PSCAD simulation on a 500MW 200kV/600kV DC/DC test converter.
