Reserch On Conversion And Storage Technology Of Motion Body Vibration Energy To Electric Energy

Today,economic develops rapidly,the need for energy increases.However,the conventional energy resources what can recovered are limited,more and more people recognize the energy crisis.The supply of adequate energy is the foundation of social development.So,the top priority is how to use the new energy fully and effectively.Owing to the vibrational energy exists widespread.A converter device was designed to turn the motion's vibrational energy to the electrical energy, and studies the follow-up segments using this electrical energy.Firstly,this paper sets about from a basic principle,the induction coil induces electromotive making use of the relative motion between the permanent magnet and the induction coil,then determines the material, the structure and the main parameters of the permanent magnet and the induction coil, designs the structure of the generation device and simulates in the sofeware.Because of this electromotive charges up the mobile phone using as a backup power,the voltage of the mobile phone battery is 3.7V-4.2V,the charging voltage should be higher than 4.2V. This can be a basis for designing of the double voltage rectifier,the filter and the voltage stabilizing circuit, achieving the requirement for the charging voltage of the mobile phone.Finally,the storage module of the electrical energy was designed and the principle of work of the double voltage rectifier circuit was analyzed,the filter circuit and the voltage stabilizing circuit as well as the choice of all of circuit element.Then uses the pspice simulation software to set up the simulation model of the double voltage rectifier circuit,the filter circuit and the voltage stabilizing circuit and obtain the simulation results.The simulation results verify the feasibility of the theoretical.
