Abstract

© 2015, Springer Science+Business Media Dordrecht. The last decade has witnessed increasing developments on multilevel converters to rectify the problem of high power processing via switch mode converters. The outcome of these advances is expressed by many innovative topologies such as DC–DC multicellular converter. This paper investigates a state feedback stabilization of two-cell converter limit cycle through hybrid dynamic systems theory. For this purpose, a desired limit cycle is firstly defined by an analysis of PWM control technique. Then, the state feedback is developed using hybrid automaton formalism, which allows us to design independently a transitory-state control scheme and steady-state control scheme. Finite-time stability of the desired limit cycle is proved analytically. Simulation results confirm the theoretical results and show the robustness of the proposed controller in spite of different perturbations. Furthermore, the proposed hybrid controller can be extended to other multilevel converters.
