Design of MVDC converters- Notions, Reliability and ROI

When it comes to MVDC converter design, reliability is a key aspect in the selection of converters and you need to identify the optimal configuration which gives maximum return of investment (ROI) to the asset owner. Check out our essential design features.

Comparison of three Converter Configurations

Three candidate multi-level topologies namely three-level neutral point clamped converter (3L-NPC), modular multi-level converter (MMC) and cascaded 3L-NPC (which is being used for the first MVdc link in the UK) have been evaluated over two-level-VSC from ±10 kV to ±50 kV.

Comparison of five characteristics of VSCs at different MVdc voltage levels (a) ±10 kV; (b) ±27 kV; (c) ±50 kV shown below
