Abstract

In this study, an advanced energy harvesting interface called synchronized switch harvesting on inductor (SSHI) has been integrated with a piezoelectric energy harvester on a plate-like structure for multimode energy harvesting purposes. To the best of author’s knowledge, this type of energy harvesting system has not been studied in the literature before. Analytical solution has been developed to predict the power output of the harvester. Besides, experiments have been performed to validate the analytical model predictions and evaluate performance of the circuit. The experimental results showed that the SSHI circuit has three different switching behaviour, namely, no switching, single switching, and multi-switching. Power output of the SSHI circuit has been compared with AC-DC rectifier. It was shown that the SSHI circuit improves the power output of the harvester for the first two vibration modes of structure in the single switching case. The SSHI circuit acts as a rectifier in no switching case. Finally, multi-switching dissipates the available energy of harvester and reduces the output voltage and power of the harvester.
