Abstract
An optimized structure of an arm capacitor voltage balance controller based on chain links of the H-bridge module that achieves enhanced performance of an arm capacitor voltage balance control in all operational conditions, even with highly dynamic loads. Such a controller has application in three-phase STATCOM converters, and may be structured so as to seamlessly integrate feedforward and feedback controls with inverse maps used for calculation of the zero sequence reference voltage injection(s) (for star and delta STATCOM topologies).
