Enhanced Power Management System Powered by Piezo Electric Energy Harvesters for Data Transmission Systems

This paper presents an enhanced power management system (PMS) for data transmission applications. The presented EHS is based on a low power non-inverting buck-boost converter and provides maximum power point tracking and protection features. Compared to previous implementations [1]-[4], the presented PMS improves efficiency by up to 50%, reduces first transmission time by 35% and periodic transmission time by 17%.
