基于PVDF双发电系统的研究

摘要

In response to the goverment's energy-saving and emmition reduction policy, a novel pressure power generation system for environmental protection was designed. Based on the piezoelectric effect of materials, the electrodynamic force can be quickly generated through the vibrdtion and air pressure acting on piezoelectric material PVDF, and the energy accumulation is realized. The two generation sections system works simultaneously. The captured vibration energy is collected by a power grid, then is boosted by a low input booster circuit to achieve the minimum working voltage for accumulation energy circuit, so as to collect the accumulated energy by an energy accumulated circuit and realize the power generation. The power generator mainly consists of three parts:moving pressure power generation, compressed air power generation, and boost accumulation circuit.%为了响应国家节能减排新政策,设计了一种新型、环保节能的压力发电系统,基于材料的压电效应,利用运动压力和空气压力双作用于压电材料PVDF便可快捷地产生电动势,实现发电效果.系统可以同时进行两部分发电,所捕获的振动能量通过电网集中收集,再通过超低输入升压电路进行升压,以达到储能电路的最低工作电压,从而通过储能电路收集储存电能,实现发电.整个发电系统主要由运动压力发电部分、压缩空气发电部分、升压及储能电路部分三大部分组成.
