Designing a low voltage energy harvesting interface circuit utilizing piezoelectric vibration transducer

摘要

This paper presents designing a low voltage energy harvesting interface circuit utilizing piezoelectric vibration transducer (PVT). PVT with energy harvesting interface circuit (EHIC) is considered as an alternative power source to run the low power devices, especially for remote area where power is unavailable. A method (i.e., switch-mode boost converter) has chosen for designing the low-power EHIC for micro devices applications. The PVT has been analyzed with different frequency and the output voltage of PVT is used as an input source to design EHIC. The EHIC consists of non-controlled rectifier, filter, switch-mode open loop boost converter and an energy storage device with capacitor at the output terminal. Finally, the complete EHIC has designed and simulated using Matlab Simulink software.
