Abstract

The Modular Multilevel Converter (MMC) is nowadays an attractive technology. However, due to the power pulsation in each MMC single phase unit it requires big DC capacitors. This work presents a control strategy for a 3-phase AC/DC Asymmetric Alternate Arm Converter with MMC arms in the lower side and only standard ON-OFF valves in the upper side. The topology operation principle is explained, a control strategy to demonstrate its operation is developed and a preliminary evaluation of the topology losses is carried out. Results confirm good operation of the suggested topology. Moreover, a sort of interleaved operation is proposed in order to reduce the DC link ripple current resulting from the converter control strategy.
