One-Dimensional Maximum Power Point Tracking Design of Switched-Capacitor Charge Pumps for Thermoelectric Energy Harvesting

Maximum power point tracking for optimizing energy harvesting process

There has been a growing interest in using energy harvesting techniques for powering wireless sensor networks. The reason for utilizing this technology can be explained by the sensors limited amount of operation time which results from the finite capacity of batteries and the need for having a stable power supply in some applications. Energy can be harvested from the sun, wind, vibration, heat,...

Analysis and Design Strategy of On-Chip Charge Pumps for Micro-power Energy Harvesting Applications

Charge balance law based on conservation of charge is stated and employed to analyze on-chip linear, Fibonacci and exponential charge pumps. For micro-power on-chip implementations, both the positiveand the negativeplate parasitic capacitors have to be considered. Voltage conversion ratios and efficiencies can be obtained in closed form for singleand dual-branch linear charge pumps, but not for...

Low Power PMIC Design with Regulated Output Voltage and Maximum Power Point Tracking for Body Heat Energy Harvesting

Maximum Power Point Tracking of Wind Energy Conversion System using Fuzzy- Cuckoo Optimization Algorithm Strategy

Nowadays the position of the renewable energy is so important because of the environment pollution and the limitation of fossil fuels in the world. Energy can be generated more and more by the renewable sources, but the fossil fuels are non-renewable. One of the most important renewable sources is the wind energy. The wind energy is an appropriate alternative source of fossil fuel. The replacem...

Control Models of Switch Mode Maximum Power Point Tracking Interfaces for Energy Harvesting Devices

In this paper, we present a method to model and control the interface electronics in order to obtain maximum power transfer from a rotational energy harvester. A state-space representation of a boost converter (with component parasitics) was derived and embedded in a control loop that performs input impedance matching to the armature resistance of the rotational harvester. Root locus techniques...
