摘要
分析了松耦合变压器的特点,利用有限元模型分析了铁芯材料、线圈位置、气隙大小对变压器耦合系数的影响,并通过实验验证了模型的正确性。同时针对原/副边漏感的特性进一步讨论了原/副补偿问题,并给出了具体的补偿网络。
Using FEA model, it analyzes the variation of coupled coefficient with the coil material, the position of windings and the length of air - gap. A prototype is also designed and the experimental results prove the FEM model well. Then it researches the compensation networks in primary and secondary winding. This can provide important reference for design of loosely coupled transformer in inductive power transfer system.
