One dimensional feed-forward modulation of a cascaded H-bridge multi-level converter including capacitor balancing with reduced switching frequency
(IEEE, 2011)
Multi-level converters are well suited to medium and high power applications where the priority is for high quality a.c. currents with low harmonic content and for low switching losses. Suitable modulation schemes must ...
