Mixed cells modular multilevel converter [PDF]
2014 IEEE 23rd International Symposium on Industrial Electronics (ISIE), 2014 This paper uses a scaled down version of the mixed cells modular multilevel converter (MMC) to discuss its modulation and capacitor voltage balancing method, and investigates its AC and DC fault ride-through capability. It has been found that the mixed MMC is resilient to both AC and DC network faults, which are necessary for next generations of highly
