Abstract:
This paper presents a new technique of electrical energy generation using mechanically excited piezoelectric materials and a nonlinear process. This technique, called Double synchronized switch harvesting (DSSH), was derived from the synchronized switch damping (SSD), which was a nonlinear technique previously developed to address the problem of vibration damping on mechanical structures. This technique results in a signiï¬cant increase of the electromechanical conversion capability of piezoelectric materials. An optimized method of harvesting vibrational energy with a piezoelectric element using a dcâ€“dc converter was presented. In this configuration, the converter regulates the power flow from the piezoelectric element to the desired electronic load. Analysis of the converter in discontinuous current conduction mode results in an expression for the duty cycle-power relationship. Using parameters of the mechanical system, the piezoelectric element, and the converter; the â€œoptimalâ€ duty cycle can be determined where the harvested power was maximized for the level of mechanical excitation. . A circuit was proposed which implements thisrelationship and experimental results show that the converter increases the harvested power by approximately 365% as compared to when the dcâ€“dc converter was not used.
