| Abstract |
This paper presents a predictive strategy for current control of a three-phase flying capacitor converter.Future values of the load current and flying capacitor voltages are predicted with discrete-time systemmodels. An offline solution for obtaining the best one of the 19 possible voltage vectors is combined witha hysteresis-based voltage balancing algorithm which makes use of the redundancy of the 64 switchingpossibilities of the converter. With few modifications this principle can easily be extended to inverterswith a higher number of voltage levels. |
