Abstract

For multi-input piezoelectric energy harvesting, the issue of energy backflow between multiple Piezoelectric Transducer (PTZ) cause energy loss. Hence, an Isolated Active Rectifier (IAR) is proposed in this paper to address the problem. Based on the characteristic of energy isolation, the Multi-Input Synchronous Electric Charge Extraction Circuit (MI-SECE) with IAR can harvest energy from multiple PZTs with the arbitrary phase difference. The peak overall power conversion efficiency can reach up to 85.5%.
