摘　　要：为加强无线电能传输(WPT)系统中继线圈的灵活性,从而突破更多的物理条件限制,引入了偏置线圈的概念。将发射线圈和中继线圈或者中继线圈和接收线圈视为一个整体线圈,通过求解阻抗矩阵行列式,得出了整体线圈新的谐振频率,避免了两线圈因为距离太近引起的频率分裂对功率传输的影响。最后设计制作了一套带中继线圈的磁共振WPT系统实验装置,通过实验验证了所提方法的正确性和可行性。In order to strengthen the flexibility of relay coil in the wireless power transmission （WPT） system and break through the more limitations of physical conditions, so the concept of the biased coils are introduced.Treat the transmitting coil and the relay coil or the relay coil and the the receiving coil as a whole coil,the whole coil＇s new resonance frequency is obtained by solving the impedance matrix determinant, thus avoiding the power loss because of frequency splitting that the two coils are too close.The final design with a set of the experimental device of the WPT system with a relay coil, and the experimental results verify the correctness of the above analysis.
