Abstract

There has been a significant increase in the research on energy harvesting device for low power applications in recreant years. This is due to smaller electronics power applications such as wireless and mobile electronics and the demand for better lifespan of batteries. One of the challenges of the harvesting energy from ambient is to convert, transfer and store the usable power effectively. In this context, there is a need to understand and design and efficient energy harvesting power management circuitry. In view of the issues, this paper compares several energy harvesting power management techniques and applications. Based on the comparison, suggestion on the design improvement are also included. This paper proposed improvement on the adaptive circuit as to get better efficiency. This paper will propose by using full bridge AC-DC rectifier to convert AC input voltage to usable DC voltage. In order to reduce power consumption of the circuit and power losses, comparator circuit is implementing as an adaptive approach to the DC-DC step-down converter. Simulation results are presented that output voltage from power management energy harvesting circuit is 3.0V with output power is 30mW. The efficiency reported as 80%. The total power losses are 7.5mW. Lastly this design presents a stand-alone system, single supply voltage and compatibility for micro-scale circuit integration.
