Abstract
In recent years, energy depletion and alternative energy issues gradually are taken seriously, the piezoelectric material security, good stability and small size of the advantage, making it an important alternative energy sources.
The energy derived from the piezoelectric power harvester could be applied to the circuit of Synchronized Switch Harvesting on Inductor (SSHI) successfully. Moreover, by allocating the energy into two parts, one for SSHI circuit, the other for electric components, the energy is enough to supply the whole circuit, which makes it become a self-powered system with high efficiency. In this paper, the method of electromagnetic induction is used to drive the switches because its produced signals have low noises. This advantage makes it easier to control, decreases the design of filter circuits in the whole system and deduces the energy consumption.
