In order to improve the transmission performance of the wireless power transfer (WPT) system under misaligned conditions, a novel type of dual-channel DDP type transmitter coil is proposed inspired by the traditional LCC compensation circuit and DD coil. The proposed DDP coil is a combination of DD coil and P coil, which jointly establishes the main flux for magnetic coupling and power transmission. At the same time, the P coil also acts as the resonant inductor of the LCC compensation circuit of the WPT system. When the system parameters are well designed, we can achieve relatively more stable output current during the offset of the primary and secondary sides. Experimental results indicate that when the misalignment varies from 0 m to 0.15 m, the output current variation range is 2.92 A to 3.68 A, the current fluctuation rate is 11.5%. Compared with the traditional DD coil with LCC topology, the proposed dual-channel transmitter DDP coil shows better performance in misalignment tolerance.

用于无线功率传输系统的强偏差容差双通道耦合器


为了提高非对准条件下无线功率传输（WPT）系统的传输性能，受传统LCC补偿电路和DD线圈的启发，提出了一种新型双通道DDP型发射线圈。所提出的DDP线圈是DD线圈和P线圈的组合，共同建立磁耦合和电力传输的主磁通。同时，P线圈还充当WPT系统LCC补偿电路的谐振电感。当系统参数设计得当时，我们可以在原副边偏置时获得相对更稳定的输出电流。实验结果表明，当错位在0 m~0.15 m范围内变化时，输出电流变化范围为2.92 A~3.68 A，电流波动率为11.5%。与具有LCC拓扑的传统DD线圈相比，所提出的双通道发射器DDP线圈在未对准容差方面表现出更好的性能。
