Vibration Powered Generators and Power Processing Circuits for Energy Harvesting: A Survey
This paper presents a survey on vibration powered generators and power processing circuits for energy harvesting. Vibration powered microgenerator, which harvest mechanical energy from environment and convert this energy into useful electrical power. This survey starts by introducing micro - energy harvesters and their use, it is then explained the way these devices obtain energy from the environment. Different microgenerators that will obtain the energy from vibrations are presented. This paper is focused on using the principle of electromagnetic induction for the generation of electrical power from low frequency vibration in the environment. And also a number of suitable converter topologies for low voltage, low power energy harvestings are presented. Significant challenges in converting the power and novel converter topologies for low voltage microgenerators are also highlighted in this paper. Multiple methods to interface the microgenerator with the converters are presented.
