Abstract
In order to solve the problems of large air gap and magnetic leakage in magnetic circuit of electromagnetic vibration energy harvester,a kind of vibration energy harvester with single degree of freedom based on magnetic conductive material is de-signed and presented in this paper.The harvester system is equipped with a magnetic yoke and an armature,which can increase the system's magnetic induction by closing the magnetic circuit and reducing the magnetoresistance,reducing magnetic leakage and en-hancing the system's energy efficiency,the vibration energy harvester outputs a higher induced voltage and converts the vibration en-ergy in the environment into electrical energy.In this paper,the system model is analyzed through the finite element simulation.The simulation results show that the armature and the magnetic yoke have obvious enhancement effect on the magnetic induction,the magnetic induction of the finite element model with yoke and armature is 2.53 times higher than that of the finite element model with-out yoke and armature,and the open-circuit voltage is 354.8%higher than the magnetic induction value of the finite element model without armature and yoke.By optimizing the parameters of the vibration energy harvester,it is found that the output power of the system reaches its maximum when the number of turns is 1 300,the length of the coil is 134.67 m,the thickness of the upper and lower parts of the magnetic yoke is 21 mm,and the thickness of the middle part is 5.5 mm,the maximum output power is 0.403 W.关键词
