Sequential Phase-Shifted Model Predictive Control for Modular Multilevel Converters
(2021)
Model predictive control has emerged as a promising approach to govern modular multilevel converters (MMCs), due to its flexibility to include multiple control objectives and simple design process. However, this control ...
Dynamic DC-Link Voltage Control of Back to Back Modular Multilevel Converter for Drive Applications
(IEEE, 2019)
In this work a dynamic control of the dc-link voltage in a hybrid Back-to-Back (BtB) Modular Multilevel Converter for medium-voltage drive applications is presented. The proposed control scheme relates the speed of the ...
Circuit Topologies, Modeling, Control Schemes, and Applications of Modular Multilevel Converters
