“…The principles of operation of the series SSHI (Taylor et al, 2001;Lefeuvre et al, 2006a) are a little bit different than in the case of the parallel SSHI. Actually in the case of the series SSHI, the harvesting process occurs at the same time than the inversion process ( Figure 6), this latter being done with respect to +V DC (switching from positive voltage) or −V DC (switching from negative voltage).…”

“…Now the basic principles of the nonlinear conversion enhancement exposed, this section proposes the direct application of this concept to energy harvesting, leading to the concept of Synchronized Switch Harvesting on Inductor Lefeuvre et al, 2006a;Shu, Lien and Wu, 2007;Liang and Liao, 2009;Qiu et al, 2009b). Considering the standard energy harvesting interface that consists in connecting the piezoelectric element to a smoothing capacitor C S and load R L (that represents the connected device) through a diode bridge rectifier (Figure 4(a)), the switching element may be placed in two ways: When using the standard interface, it can be demonstrated that the harvested energy under a constant vibration magnitude u M is given in steady state case by : …”

“…For lowly coupled piezoelectric harvesters, it has been demonstrated that synchronous strategies like Synchronous Electrical Charge Extraction (SECE) are promising and exhibit higher performances than classic electronic interfaces, such as a diode rectifier followed by a buck-boost converter [1][2][3]. However, for highly coupled or lowly damped generators, SECE is no longer efficient since it overdamps the mechanical system.…”

Abstract-This paper proposes a new strategy for vibration harvesting using piezoelectric material. This work relies on an adaptation of the classical Synchronous Electrical Charge Extraction (SECE). Instead of harvesting the energy at every displacement extremum, we choose to wait a certain number of extremum before harvesting the accumulated energy. This technique extends the harvested power compared to SECE, especially with highly coupled piezoelectric generators. It is notably shown that this strategy largely increases the harvested power as the product k m 2 Q m gets greater, and at the same time optimizes the switching losses. Measurements on a piezoelectric energy harvester (PEH) exhibiting a relatively large global coupling coefficient have been realized and have proven the efficiency and potential of this technique (193% harvested power improvement at resonance compared with a standard SECE strategy).

Energy Harvesting is a pro mising solution for powering Structural Health Monitoring (SHM ) systems since various mechanical energy sources are generated by aircraft. Today, the main technique to harvest energy consists of using a specific conversion device to provide power to the SHM system. In this paper however, a novel technique to obtain a self-powered SHM system for aeronautical structures is proposed. This SHM system aims to have a double functionality: it will carry out classical SHM tasks using piezoelectric transducers bonded onto the aircraft structure and will also be fully autonomous since the same transducers will convert the mechanical v ibrations of the structure into electrical power. Using a bonded piezoelectric t ransducer to harvest energy will also bring wideband frequency energy harvesting capability. Th is autonomous system using a unique transducer being particularly innovative, the objective of this paper is to provide a complete Bond Graph model of the energy harvesting process in order to allow the optimisation of its performances. This approach is well-suited to monitor the power and energy transfer carried out during the process since it takes into account the interaction between mu ltiphysics systems, here the electrical and mechanical domains in terms of power and energy variables. Consequently, each part of the energy harvesting, i.e. the mechanical v ibration of the host structure, the vibration within the SHM energy harvester volume, the piezoelectric electro mechanical conversion and the terminal electric load have been modelled analytically using this Bond Graph approach. Then, each submodel has been verified with a baseline Fin ite Element model. Good agreements have been found and it has been possible to carry out an estimat ion of the power harvested by the SHM energy harvester for a given mechanical excitation using this innovative complete analytical Bond Graph model.
