Abstract
In this article, a rectifier-less synchronized switch harvesting on inductor (ReL-SSHI) interface circuit for piezoelectric energy harvesting is presented. The proposed circuit works in two different modes: at the positive peak of the open-circuit voltage of the piezoelectric transducer (PZT), the switch in series with the load is turned on, and is operated in the series synchronized switch harvesting on inductor mode; at the negative peak of the open-circuit voltage of the PZT, the switch in parallel with the load is turned on, and is operated in voltage synchronous inversion mode. The ReL-SSHI circuit does not need a rectifier bridge so that the power loss of the circuit is reduced, and hence the piezoelectric energy harvesting efficiency of the circuit is improved. Theoretical analysis and simulation verify the effectiveness of the ReL-SSHI circuit.
