A Piezoelectric Energy-Harvesting System with Parallel-SSHI Rectifier and Integrated MPPT Achieving 417% Energy-Extraction Improvement and 97% Tracking Efficiency
This work presents an integrated maximum-power-point tracking (MPPT) algorithm and its implementation for the high-performance parallel-synchronized-switch harvesting-on-inductor (SSHI) rectifier, which uses the Perturb and Observe (P&O) method and a proposed power monitor for output power evaluation. Fabricated in 130nm, this piezoelectric energy-harvesting system implements a 417% FOM rectifier with 97% tracking efficiency MPPT, which makes it the first work demonstrating a parallel-SSHI rectifier and high tracking-efficiency MPPT simultaneously.
