摘　　要：建立了悬臂梁式压电能量收集器的机电模型,并用电磁仿真软件ANSOFT仿真大电流下的母排周围的磁场分布情况,随后利用ANSYS对压电效应进行仿真分析,最后根据模型设计了基于LTC3588-1的管理电路,使得压电输出能够被收集利用。The electromechanical model of cantilever beam based energy collector is established, and ANSOFT is used to simulate the magnetic field distribution around the bus bar excited by the high current. Then, simulation analysis of pi- ezoelectric effect is done by means of ANSYS. Finally, management circuit based on LTC3588 - 1 is built according to that electric model, so that power out from the piezoelectric unit can be collected and utilized.
