High voltage direct current (HVDC) technology become crucial for power systems because of its benefits including less losses, easier asynchronous grid connections, improved controllability, higher system availability, and less short-circuit currents. Recently, several innovative converter topologies have been proposed to connect medium-voltage to high-voltage systems. Many of these topologies are based on chain-link or modular concepts, which offer scalability across different voltage and current ranges while maintaining high reliability, feasibility, and power quality. This article aims to analysis a comprehensive review of recent isolated DC/DC converters topologies based on modular multilevel converter (MMC) for MVDC to HVDC interconnections. A comparative analysis of these topologies is conducted to ascertain their configuration, operating principles, as well as their advantages and limitations. These analyses will be helpful in identifying the most suitable topology for a particular application.
