The power converters are more and more implanted to optimize the energetic properties of electrical systems. This paper concerns the control of commutations for a multicellular converter through a hybrid approach. Compared with a classical converter (H-bridge), the structure of the multicellular converter enables a more accurate regulation. In this kind of converter, a complete regulation of the state is required to ensure the tracking of the load current and a suitable distribution of the capacitor voltages across each cell. Using the hybrid formalism, the dynamics of the system is characterised by a set of modes. The aim is to design a binary controller which achieves the state regulation. The switching conditions of the control law are determined by a Lyapunov function. In this approach, adjacency constraints are considered in the hybrid model to improve the performances of the converter. An experimental comparative study with the classical pulse-width-modulation strategy highlights the efficiency and the robustness of the proposed approach. |
