Power Point

To improve conversion efficiency and output quality of the energy harvester, a novel interface circuit with composite maximum power point tracking (MPPT) in energy harvesting applications is proposed in this paper. By using the ultra-low-voltage multiplier with digital control and simple one-cycle variable frequency technique, the converter realizes fast power tracking and high conversion efficiency, and minimizes the power consumption and harmonics, thereby obtaining high tracking precise and low total harmonic distortion (THD). Implemented in 65-nm CMOS process, this converter achieves 85.9% peak power efficiency with dc output voltage of 1.6[Formula: see text]V. The peak tracking efficiency and THD are 99.2% and 1.3%, respectively. The peak output power is 18.31[Formula: see text][Formula: see text]W, and the power loss of the entire converter is only 16.53[Formula: see text][Formula: see text]W.

Review Current

The goal of this paper is to review current methods of energy harvesting, while focusing on piezoelectric energy harvesting. The piezoelectric energy harvesting technique is based on the materials’ property of generating an electric field when a mechanical force is applied. This phenomenon is known as the direct piezoelectric effect. Piezoelectric transducers can be of different shapes and materials, making them suitable for a multitude of applications. To optimize the use of piezoelectric devices in applications, a model is needed to observe the behavior in the time and frequency domain. In addition to different aspects of piezoelectric modeling, this paper also presents several circuits used to maximize the energy harvested.

Energy Harvesting System

In this paper, the frequency broadband effect in vibration energy harvesting was studied numerically using a quasi-zero stiffness resonator with two potential wells and piezoelectric transducers. Corresponding solutions were investigated for system excitation harmonics at various frequencies. Solutions for the higher voltage output were collected in specific branches of the power output diagram. Both the resonant solution synchronized with excitation and the frequency responses of the subharmonic spectra were found. The selected cases were illustrated and classified using a phase portrait, a Poincaré section, and recurrence plot (RP) approaches. Select recurrence quantification analysis (RQA) measures were used to characterize the discussed solutions.
