Assessment of Power Electronics Converters for HVDC series tapping station

This article assesses the power electronic converters for HVDC tapping stations. Firstly, it compares parallel and series tapping stations to show the potential benefits of the last ones. Then, an original series converter based on a Current Source Alternate Arm Converter (CSAAC) is compared to a common Voltage Source Modular Multilevel Converter (VSMMC). It shows that the former requires little industrial effort whereas the latter, less mature, outperforms its predecessors in many criteria.
