Abstract
Multicellular converters appeared for a few years in order to palliate some drawbacks of the classical structures. Such structures allow to reduce the voltage throughout the switches and the number of discrete values of the voltage in the load is directly related to the number of commutation cells. In opposing view, the control of a multicellular converter is more complex. In this paper a generic controller for a multicellular serial converter is developed, based on a generalization of Passivity Based Control fitted to bond graph formalism. The generic state equations are deduced from the original bond graph model using the notion of commutation cells. The whole approach is presented in a formal way and the performances of the controller realised will be tested on an example.
