摘要:
Rectifier-Less Synchronized Switch Harvesting on Inductor (ReL-SSHI) interface is one of the most efficient in-terfaces for weakly-coupled piezoelectric (PE) systems. However, ReL-SSHI interface has narrow optimal recti-fied voltage range. Therefore, in this paper a maximum power point tracking (MPPT) circuit is presented for ReL-SSHI interface. An envelope extractor and a hysteresis voltage controller are used in the MPPT, which can monitor the open circuit (OC) voltage of piezoelectric transducer (PZT) during Energy Harvesting (EH). Simu-lation shows the maximum MPPT efficiency can reach up to 99.1% and the Figure of Merit (FoM) factor can achieve 6.4. The measurements confirm the simplicity and efficiency of the proposed MPPT solution for the weakly-coupled piezoelectric energy harvesting (PEH).
