The design phase of a modular multilevel converter (MMC) needs to be supported by suitable tools for the submodule loss evaluation. This paper proposes a fast MMC cell loss calculation based on the virtual submodule (VSM) concept. The Modular Multilevel Converter system offers many advantages over conventional voltage source converters. Discover OPALRT MMC solutions. MULTILEVEL MODULAR valve inductor to ground and between submodules of different valve Turnkey Modular Multilevel Converter (MMC) Test Bench for Rapid Control Prototyping and Laboratory Research AbstractA modular multilevel dcdc converter fed with However, the current ratings in different submodules are not the same, and the inductor currents close to the lowvoltage side are high. stepup conversion is provided to demonstrate the concept. modular multilevel converter with different submodule concepts Modular Multilevel Converter With Different Submodule ConceptsPart I: Capacitor Voltage Balancing Method Abstract: This paper presents a modulation strategy for the modular multilevel converter (MMC) which provides the voltage balancing of the capacitors of different submodules comprising the converter. The Modular Multilevel Converter (MMC) represents an emerging topology with a scalable technology making high voltage and power capability possible. The MMC is built up by identical, but individually controllable submodules. Therefore the converter can act as a controllable voltage source, with a large number of available discrete voltage steps.
