摘要
压电式能量俘获器的接口电路能否实现电能的高效转换,一直是制约能量俘获器的关键问题。通过理论分析在能量俘获系统中建立等效模型并推导出系统的控制方程,将目前几种典型接口电路的工作原理进行了对比研究,归纳总结了各自的特点、实用性和优势,为今后能量接口电路的研究提供了理论依据。
Whether the interface circuit of piezoelectric energy capture device can realize the efficient conversion of electric energy is the key problem that restricts the energy capture device.Through theoretical analysis,the equivalent model is established in the energy capture system and the control equation of the system is derived,the working principles of several typical interface circuits are compared,and their characteristics,practicability and advantages are summarized,which provides a theoretical basis for the research of energy interface circuits in the future.
