To overcome the drawback of low output voltage across the small optimal load, it is proposed to use the transistor-based rectifier biased by the self-powered SECE-based piezoelectric energy harvester (PEH). In addition, the buck-boost converter controlled by the self-powered SSHI-based PEH is implemented for the maximum power point tracking. A semi-analytic model is developed for predicting the peak power and the optimal load used for designing the buck-boost converter. The prediction is then validated by experiment showing 1.5 mW optimal output power. Further, it is found that the 0.22 low rectified voltage is increased up to 2.5 V by the proposed SSHI-based voltage boosting technique. It offers advantages of zero quiescent power dissipation and the ease of tuning the input impedance of the buck-boost converter by varying the SSHI load impedance. ? 2021 SPIE. All rights reserved. |
