The cascaded H-bridge converter (CHB) and the modular multilevel converter with chopper or bridge cells (CC or BC) are two highly discussed multilevel topologies in power storage applications. The CHB converters, shown in Fig. 6, consist of several cells of single-phase H-bridge converters connected in series in each phase [35, 36, 37].
