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.
