   In this article, the diagnosis of a three cell converter is developed. The hybrid nature of the system represented by the presence of continuous and discrete dynamics is taken into account in the control design. The idea is based on using a hybrid control and an observer-type sliding mode to generate residuals from the observation errors of the system. The simulation results are presented at the end to illustrate the performance of the proposed approach.

Keywords: multicellular converter, diagnosis based-observer, hybrid observer, residual, cell fault sliding mode, hybrid dynamical systems
