Modular Multilevel Converter (MMC) is a promising topology for high voltage/power AC/DC and DC/AC applications. Model Predictive Control (MPC) is an advanced and simple method for power converters control. However, its computational load becomes unacceptable when MMC voltage level increases. An improved MPC for MMC is proposed in the paper. The submodule capacitor voltages are sorted according to...
Power Electronic Transformer (PET) is one of the most prospective components for future power electronics based power distribution systems. In this paper, the issue of the series-connected voltage sharing and the parallel-connected current sharing of a three-stage H-bridge based PET is discussed. Based on the present overall control strategy and application, it finds that the output-stage parallel-connected...
