摘要
介绍了基于压电效应的标准能量采集电路,在此基础上设计了并联电感同步开关能量采集电路,通过理论分析和计算,建立了该电路的输出功率数学模型。通过ANSYS压电耦合分析及MULTISIM(电路仿真软件)电路仿真,得到并联电感同步开关能量采集电路比标准能量采集电路的输出电压高出1倍,输出功率高出400%。
The criteria energy collection circuit based on piezoelectric effect was described,on which synchronized switch harvesting circuit of shunt inductor was designed.The math model of power was built by theoretic analysis and calculation in this paper.After the piezoelectric coupling analysis of ANSYS and simulation of MULTISIM,the result revealed that,comparatively with standard technique,the output voltage was increased by 100%,and the electrical power harvested could be increased by 400%.
