Photovoltaic Energy Harvester with Power Management System

Photovoltaic Energy Harvester with Power Management System

The reduction trend of modern microsystem power consumption is balanced by the constant growth of complexity. Traditional batteries are, therefore, no longer sufficient for many applications, since they cannot guarantee a long enough life time [1]. By harvesting energy from the environment, such systems could work for nearly infinite time without the need of replacing batteries. In this paper w...

Smart Adaptive Power Management in Electrostatic Harvester of Vibration Energy

This paper reports a new functional design and modeling of a vibration energy harvester composed from a mechanical resonator (MEMS), capacitive transducer and a conditioning circuit based on the BUCK DCDC converter architecture. The basic configuration of conditioning circuit from [1][2] is enhanced with two major features for the power management allowing, firstly, to adapt dynamically to the ...

Wireless Power Transfer System For A Human Motion Energy Harvester

Human motion energy harvesting as an alternative to battery powering in body worn and implanted devices is challenging during prolonged periods of inactivity. Even a buffer energy storage system will run out of power eventually if there is no external acceleration to the harvester. This paper presents a method to actuate the rotor inside a previously presented rotational piezoelectric energy ha...

Smart energy management system for utility source and photovoltaic power system using FPGA and ZigBee

Renewable energy resources are being used to overcome energy shortage. From the point of view of energy management the interconnectivity of electric utility with renewable energy resources is difficult. Renewable energy resources need to be managed with electric utility. A Smart Energy Management System (SEMS) is designed and developed for monitoring an efficient load management of electric uti...
