PERFORMANCE MEASURE OF SERIES-PARALLEL PIEZOELECTRIC TRANSDUCER CIRCUITY FOR IMPROVEMENT OF OUTPUT VOLTAGE
Keywords:Piezoelectric Transducer (PZT), DC chopper, invertor, AC regulator, Bridge rectifier
This project presents a comparative study between power generation using piezoelectric transducers available in the literature and the proposed model design. The parallel and series-connected piezoelectric transducers arrangement in this project, when subjected to mechanical stress (footsteps), generates an electric charge. The power generated from piezoelectric transducers will be given as input to bridge rectifier and chopper for conversion to dc quantity and its amplification respectively. This energy will be stored in a Li-ion battery. The paper mainly highlights aspects of improvement of power generation by optimizing circuit design and adapting output enhancement and amplification. Comparative analysis of power generated from predecessor circuit designs and output voltage obtained from current circuit design is validated and presented
