This paper deals with the development of strategies of observer and controller which allows the balancing in a close loop of the floating voltages of a multi-cellular converter. More specifically, a sliding mode control algorithm and observer is designed for the floating voltages in the multi-cellular converter. The first part of the paper deals with the importance implementation of a sliding mode control algorithm. In the second part a topology with a sliding mode observer and controller of multi-cell converters is proposed. The performance and the validity of the controller and observer are shown by simulation.
