摘要：

Modular Multilevel Converters (MMCs) are attracting considerable interest for high-power and medium voltage applications due to several advantages, such as reduced THD grid current, high voltage blocking, etc. However, one of the major drawbacks of this topology is the existence of the circulating current which increases the power losses and reduce the efficiency of the converter. In this paper one approach to reduce the circulating current is shown. The approach is based on resonant controllers. The resonant controller is analyzed and tuned in order to reduce the circulating current. Moreover, the controller has been tested and validated in a real processing platform designed to control large multilevel converters and in a real MMC prototype.
