In order to use the circuit of synchronized switch harvesting on inductor (SSHI)for piezoelectric energy in practice,a new self-powered SSHI circuit was proposed based on solving the static capacitance of piezoelectric energy harvester by harmonic and static analysis with the help of ANSYS.The self-powered circuit consists of the parts of energy harvesting,control voltage generating and DC power supply.The output voltage,generated by the two-step R-C shift circuit,the comparator and XOR gate,turns on the switch at appropriate time and AC-DC energy harvesting circuit supplies electric energy for low-power electronic devices,so as to achieve the function of SSHI piezoelectric energy harvesting circuit.The experimental results show that the proposed circuit can improve the energy harvesting efficiency, and provides a new and easy method for the application of SSHI in practice.
