Modular Multilevel Converter DC Fault Protection [PDF]
IEEE Transactions on Power Delivery, 2018 High voltage direct current grids will require the development of dc protections that provide fast fault isolation and minimize the disturbance caused to the existing ac power networks. This paper investigates how the dc fault recovery performance of a half-bridge modular multilevel converter (HB-MMC) is impacted by different dc protection design ...

A multilevel modular DC–DC converter topology [PDF]
Mathematics and Computers in Simulation, 2017 A multilevel modular DC-DC power conversion topology based on cascaded H-Bridge converters in a double П configuration is presented. The topology is intended to interconnect large power DC networks. A two level control hierarchy is used to regulate the DC voltage of each H-bridge module.
