access icon free Design of self-powering part of SSHI interface for piezoelectric energy harvesting

A design of the self-powering part of the synchronised switch harvesting on inductor (SSHI) interface based on zero-velocity crossing detection for a piezoelectric energy harvester is proposed and investigated. To achieve a totally self-powered energy harvester, a part of the extracted energy can be used to supply the MOSFET IC of the electric interface. The design of an extra piezoelectric element dedicated to supplying the electronics is presented. The study comprises a theoretical part and an experimental proof-of-concept demonstration of the proposed design method.
