【摘要】 松耦合感应能量传输(Loosely Coupled Inductive Power Transfer,简称LCIPT)技术结合了电磁耦合技术与电力电子技术,实现了电能的无接触传输。由于松耦合感应能量传输系统中初级与次级间存在较大的气隙,且漏感较大,自感和耦合系数低,系统的能量传输能力也低,因此需要采用补偿技术,以实现能量的高效传输。这里利用负载模型,分析并研究了系统的不同补偿拓扑对系统性能的影响。实验证实了理论分析的正确性。更多还原

【Abstract】 Loosely coupled inductive power transfer system realizes contact-less power delivery to apparatus with no electrical connection or physical contact by the combination of the inductive coupling technique and power electronics.Because of large air-gap between the primary and the secondary,this system has large leakage inductance,small magnetiz-ing inductance,poor coupling coefficient and limited power transfer capability.Compensation is usually necessary to achieve the required power transfer capability.Load models are used to investigate the effect of different compensation topology of the system.Finally,the experimental wave-forms are given,which verify the correctness of analysis.更多还原
