The modal synchronized switch damping on inductor approach SSDI-Max, maximize the self-generated voltage amplitude, by a proper definition of the switch instants, according to the chosen targeted mode. This paper presents a performance analysis of a new global approach, for improved vibration damping of smart structure based on global energy redistribution by means of a piezoelectric element network, this network topology, using diodes called SSDD-Max "Synchronized Switch Damping with Diode-Max". In this paper, simulations are performed on a model representative of a smart beam. The damping results are given in the case of multimodal, pulse excitations.
