A three-phase three-level converter with shared flying capacitors
The C 3 S keep same interests than CCIL, that is, a high number of levels for few devices (above nine levels as well as CCIL) but aims at reducing the stored energy since one cross-connected stage is used instead of three in a classic three-phase CCIL converter. Consequently, two FCs are saved.
