磁耦合谐振式供电系统的频率分裂抑制方法
摘要:
抑制谐振式供电系统发生的频率分裂在过耦合处系统效率不降低.运用耦合模理论,推导出效率与频率、耦合系数的关系式,并发现频率分裂现象.其原因为谐振线圈的品质因数发生改变.随后本文提出使用电感较大接收端的方法.此方法可以抑制频率分裂且提高传输效率.最后,组建了磁耦合谐振式供电系统实验平台,实验证明此方法有效.
In order to suppress the frequency division of the resonant power supply system, the efficiency of the system is not decreased at the over-coupling point. In this paper, the relationship between efficiency, frequency and coupling coefficient is derived by using the coupled mode theory. Subsequently,a method with a large inductor is proposed,which can suppress frequency division and improve transmission efficiency. Finally,the experimental platform of magnetic coupling resonant power supply system is established.
