Experimental Validation of 1-kV Modular Multilevel Cascaded Converter with High-Frequency Magnetic Link

In this chapter, the high-frequency magnetic-link modular multilevel cascaded (MMC) converter is experimentally validated for grid integration of renewable power generation systems. The high-frequency magnetic link generates multiple isolated and balanced DC supplies for all the H-bridge inverter cells of the MMC converter. To verify the feasibility of the converter, a scaled down 1-kV laboratory prototype test platform with a 5-level MMC converter is developed in this chapter. The design and implementation of the prototyping, test platform, and experimental results are analyzed and discussed. The methods/techniques for component selection, converter fabrication, and experimentation are also applicable to other converter applications.
