Abstract
This paper presents a control scheme for the hybrid MMCC using the 5-level flying capacitor converter as sub-module under grid unbalanced voltage condition. The hybrid MMCC is compared with the single star-connected MMCC under voltage sag condition to determine its superiority, in addition to its lower dc capacitor and power semiconductor switch count. The simulation results are provided to validate the hybrid MMCC control scheme and its comparison with the star connected MMCC.
