Generalized master-slave current tracking for multiswitching converters with predictive slave algorithm

The large number of high power conversion applications has brought to the development of complex power converter configurations constituted of the connection of two-level modules. Modulation strategies based on master-slave approach take advantage of the modularity of these power converter topologies. The present paper proposes an improved master-slave control strategy where the choice of which module has to be switched is demanded to a separate predictive slave routine. Simulation tests validate the proposed control strategy.
