Resumo
This paper presents a piezoelectric power harvesting model including both the mechanical and electrical domain. It includes a mechanical system, electrical interface, storage capacitor and load. Bridge rectifier, Parallel Synchronized Switch Harvesting on Inductor (P-SSHI) and Synchronous Electric Charge Extraction (SECE) circuits are analyzed as electrical interface. A mechanical system and control signals are implemented in VHDL-AMS and electronics components in SPICE. Simulation results and experimental data are compared to show the accuracy of the proposed model.
