Piezoelectric energy harvesting is considered as an ideal power resource for low-power consumption gadgets in vibrational environments. The energy extraction efficiency depends highly on the interface circuit, and should be highly improved to meet the power requirements. The nonlinear interface circuits in discrete components have been extensively explored and developed with the advantages of easy implementation, stable operation, high efficiency, and low cost. This paper reviews the state-of-the-art progress of nonlinear piezoelectric energy harvesting interface circuits in discrete components. First, the working principles and the advantages/disadvantages of four classical interface circuits are described. Then, the improved circuits based on the four typical circuits and other types of circuits are introduced in detail, and the advantages/disadvantages, output power, efficiency, energy consumption, and practicability of these circuits are analyzed. Finally, the future development trends of nonlinear piezoelectric energy harvesting circuits, e.g., self-powered extraction, low-power consumption, and broadband characteristic, are predicted.

“…One of its main advantages is that the power generated by PD is independent of the connected load. However, recent literature [10,[23][24][25] mainly focused on synchronous power rectification using the non-linear technique. Active rectification is not possible because the PD delivers low output power in most cases.…”

“…The motivation of this proposed study is to utilise the benefits of the conventional boost converter [31], buck-boost converter [32], and synchronous rectifier circuits [23,33,34]. As a result, the proposed circuit is expected to reduce the voltage drop in the rectification process, boost the input voltage, and minimise the ripples in the output voltage waveform.…”

Non-Linear Switching Circuit for Active Voltage Rectification and Ripples Reduction of Piezoelectric Energy Harvesters

et al. 2022

This paper describes an improved non-linear switching circuit (INLSC) for active rectification of voltage and reduction of ripples in the voltage waveform for the piezoelectric energy harvesting (PEH) system. The proposed converter controls the alternating current (AC) generated by the piezoelectric device (PD) under mechanical vibration. The proposed circuit combines the boost and buck-boost processes through a switching process, which functions in both positive and negative cycles. In addition, it controls the voltage and frequency of the load capacitor. In this process, the passive components in the circuit are energised by being short with the AC voltage using switching signals, which facilitates the active rectification of ultra-low AC voltage. Design considerations, theoretical analysis, simulations and experimental results are presented. It was shown that the circuit was able to control the switching signal and to convert low AC voltage (0.44 Vi) to high direct current (DC) voltage (6.5 Vdc) while achieving an output power of 469 µW which outperforms the existing similar circuits and synchronous rectifier circuit. The ripples in the rectified voltage were also comparatively less. Application-wise, the proposed circuit could power a manually connected 7-segments display, commonly used for traffic applications.

While some techniques such as Double Synchronized Switch Harvesting (DSSH - [23]), Enhanced Synchronized Switch Harvesting (ESSH - [24]), hybrid SSHI ( [25]), optimized SECE ( [26]) or SICE ( [27,28]) have been proposed to combine the advantages of SSHI and SECE, they still suffer from some of the drawbacks of SSHI (load dependence) and/or SECE (limited gain, complex implementation), or can raise other issues such as integrability (e.g., due to the need of electromagnetic transformer).…”

In the framework of autonomous wireless devices (e.g., sensors) powered by energy available from their surrounding environment, this paper exposes a technique combining the so-called series and parallel Synchronized Switch Harvesting on Inductor (SSHI) approaches for piezoelectric energy harvesting. More specifically, the proposed circuit consists in switching the piezoelectric element on two inductors, one in series between the piezoelement and the energy extraction stage (rectifier bridge) and the other one in parallel with the rectifier. This therefore allows energy transfer processes to occur several times per half period, even when the switching process is finished. Based on numerical analysis supported by experimental validations, it is shown that such a technique permits a significant widening of the effective load and rectified voltage ranges, but also, under particular conditions, a power output magnification that is even larger than in the sole SSHI case.
