要約(日本語): We have been proposing Star-Light Converters which overcome week points of MMCs for BTB. Star-Light converter has a structure in which cascaded converters are connected between a pair of three-phase converters. Amount of capacitors, cell numbers of Star-Light Converter, DC currents are almost half of those of MMCs. In this paper, we show behavior at AC Grid Voltage-drop. So even if the inverter terminal and converter terminal are set far from each other like HVDC, at the AC grid voltage drop of the inverter side, the converter side can know it by the system DC voltage increase and can make countermeasure of it. It might be applied to offshore HVDCs.
