Continuous model of Modular Multilevel Converter with experimental verification

The Modular Multilevel Converter is an emerging and highly attractive multilevel converter topology for medium and high voltage applications. This paper describes a continuous model of a three phase Modular Multilevel Converter. The model is derived from a system of ordinary differential equations. It can be used for a model based converter and/or control design. A comparison of simulations and experimental results using a (4.16 kV, 1MVA) induction motor drive shows the high accuracy of the proposed model.
