dc.description.abstract | This paper presents a method for switching reduction in cascaded H-bridge converters.
Given the wide applicability of this topology, it would be especially desirable to increase its efficiency with switching losses reduction techniques. Since this type of converter requires voltage
balancing methods, several modulation methods consider the possibility of combining the balancing
and switching reduction goals together. In this paper, a previously disclosed optimization-based
balance method was modified further to consider the switching losses in its objective function. Each
commutation was penalized in proportion to the phase current and the module voltage, thus avoiding
commutations that would produce the most losses but tolerating low-losses commutations. The
structure of the original method was maintained so that the algorithm could be applied with minimal
change. The results show that it is possible to reduce the switching up to 14% without any noticeable
drawback and up to 22% at the cost of a greater DC-link ripple. It is also possible to selectively reduce
the effective switching frequency of only some modules, making it significantly low. This extends
the adaptability of the converter, possibly allowing hybrid converters with modules of different
transistor technologies. | es |
