Abstract

Multilevel converters, which are supplied by cascaded capacitors and non-isolated DC sources, can not operate without capacitor voltage balancing. This paper proposes a capacitor voltage balancing technique for the dual three-level T-Type advanced converter topology. The reason behind the capacitor voltage unbalance, of this topology, is discussed and clarified by using the converter power circuit connected to an open-end three-phase load. The converter switching states are studied and classified to three different groups according to their effect on the capacitor balancing. The proposed capacitor balancing algorithm is implemented based on switching state redundancy. This algorithm was tested by simulation through Matlab/Simulink and implemented experimentally using a field programmable gate-Array digital controller. The proposed capacitor voltage balancing technique has applied to a dual three-level T-Type converter AC drive system. The simulation and the experimental results were compared and analysed. Both the simulation and the experimental results are in agreement verifying the proposed algorithm.
