title = "The Resonant Modular Multilevel DC Converters for High Step-ratio and Low Step-ratio Interconnection in MVDC Distribution Network",
abstract = "Power electronics based dc transformer is the key equipment for MVDC distribution network interconnection, which requires both high step-ratio and low step-ratio dc-dc conversions to interface dc links at different voltages. This paper reviews the original high step-ratio resonant modular multilevel dc converter (RMMC) for MVDC applications and then presents a step-by-step circuit evolution which drives the high step-ratio RMMC to a low step-ratio RMMC, which inherits all the key operational advantages that were present in high step-ratio RMMC version including soft-switching operation, inherent balancing and high effective switching frequency. Furthermore, based on these two basic RMMCs, a derivative family of RMMCs for both high step-ratio and low step-ratio conversion is provided for different kinds of interconnection requirements in MVDC distribution system. The theoretical analysis for both high step-ratio and low step-ratio RMMCs are verified by a set of medium voltage full-scale simulation examples.",
