A Bias-Flip-Based Piezoelectric Energy Harvesting Interface with a Digital Track-and-Lock MPPT Achieving Sampling-Free Operation and 99.8% MPPT Efficiency
Abstract A fully digital MPPT is proposed for a bias-flip piezoelectric energy harvester. Once the MPP is identified, its parameters are stored and locked. Even if the vibration amplitude or frequency changes or disappea

A Wireless Power Transfer System with Up-to-27.9% Efficiency Improvement under Coupling Coefficient Ranging from 0.1 to 0.39 Based on Phase-Shift/Time-Constant Detection and Hybrid Transmission Power Control
Wireless power transfer (WPT) is a convenient way to power the wearable/portable devices with water/dusty-proof requirement. The end-to-end (E2E) efficiency ηE2E is a key specification of WPT system. A compact and efficient
