A Redundancy‐based scheme for balancing DC‐link voltages in cascaded H‐bridge rectifiers
IET Power Electronics, 2013 A new voltage balancing algorithm is introduced for cascaded H‐bridge rectifiers. This kind of converter is made of a series connection of H‐bridge cells with separate dc‐links. The proposed balancing algorithm will regulate the voltage of all dc‐links to the desired reference value, even if the attached loads are very different.
