压电振动搅拌器内的流动可视化与流态分析

From the cantilever bimorph mechanical model,basic theories of piezoelectricity and mechanics were used to establish an electromechanical coupling model for piezoelectric vibration generators.

压电振动发电机是一种能量密度大、无污染、结构简单的新型供电装置。

The mini-generators like vibration generator-based piezoelectric,mini-electromagnetism effect generator,electret generator and so on have low power,it is difficult to supply the load with high instantaneous power consumption in the way of the current rectifier,filter and storage capacitor control circuit.

针对压电振动式发电机、微型电磁感应发电机、驻极体发电机等微型发电机的发电功率较小,常规的整流滤波、存储、稳压电路不能满足瞬时发射功率较大的负载供电需求问题,提出一种微功耗的电源智能管理电路的设计方案,从而使持续的微能源得以合理而有效的利用。
