摘要
松耦合变压器是非接触感应电能传输系统中的关键部分。在简要介绍松耦合变压器的基本结构和工作原理的基础上,提出了松耦合变压器的互感等效电路模型。根据松耦合变压器的特点,分析了铁芯材料、绕组位置、气隙大小对变压器耦合系数的影响。同时,针对原、副边漏感的特性,进一步讨论了变压器原、副边电路补偿问题。最后给出了非接触感应电能传输系统中松耦合变压器的耦合系数、网络补偿等几个重要参数的设计方案。
Loosely coupled transformer is a key part in contactless inductive power transfer system. For this reason, the fundamental structure and work principle of the loosely coupled transformer are introduced, and the circuit model of mutual inductance is established. Factors that affect the coupling coefficiens of the loosely coupled transformer are studied, including magnetic material, location of windings and the width of air gap. Due to the leakage inductances, compensation is necessary to achieve the required power transfer capability. The level of compensation and compensation topologies are discussed. The design proposal for main parameters of the loosely coupled transformer is suggested.
