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), is derived from the synchronized switch damping (SSD), which is a nonlinear technique previously developed to address the problem of vibration damping on mechanical structures. This technique results in a significant increase of the electromechanical conversion capability of piezoelectric materials.

Various applications of the piezoelectric energy in the modern world require an efficient AC-DC low power converter. As the two stages converter with bridge rectifiers may not be used because the diodes would not be suitable for low volt ranging between 100 to 200mv, these are considered an efficient element in the low volt circuits because of their entire losses. In this paper, a small and efficient AC-DC low power converter is presented. It directly converts low AC voltage to the required output DC voltage using one stage instead of bridge rectification. The proposed converter combines both

Abstract The low-vibration energy of raindrops is used in this paper to simulate an AC-DC converter circuit with a piezoelectric cantilever for energy collection. The piezoelectric phenomenon allows the developed piezoelectric cantilever beam to transform the little vibration energy it captures into electrical energy. The low-frequency vibration range is between 1 and 100 Hz, while higher frequencies are above 100 Hz. However, due to the inherent inconsistency in the input's magnitude, particularly in low-frequency harvesting, researchers are extensively exploring improved methods to stabilize

This paper proposes a quasi-resonant step-up DC-DC converter to provide the DC-link voltage for piezoelectric transmitters (PZETs). The resonance not only provides a soft-switching condition for the converter switches, but also helps to decrease the converter element sizes for marine applications. Operation modes of the proposed converter are discussed. The current and voltage of the converter components are derived analytically, and hence the converter gain is obtained. The performance of the proposed high-step-up, high-power density converter is examined through a comprehensive simulation st

Piezoelectric ceramics are characterized as smart materials and have been widely used in the area of actuators and sensors. The principle operation of a piezoelectric transformer (PT) is a combined function of actuators and sensors so that energy can be transformed from electrical form to electrical form via mechanical vibration. Since PTs behave as band-pass filters, it is particularly important to control their gains as transformers and to operate them efficiently as power-transferring components.
