摘要:
磁耦合感应式无线电能传输系统中补偿电容的存在使两线圈发生水平或垂直移动时产生 多个谐振频率,导致变频控制器无法识别最优频率,进而影响系统稳定性。针对此问题,在已有的 同轴线圈互感公式的基础上,依据 Neumann 公式建立偏移线圈的互感公式,分别对线圈半径、水平 偏移距离等因素与互感系数的关系进行分析。理论分析表明,增大原边线圈半径和水平偏移距离 均可消除频率分叉现象,并且增大原边线圈半径能够有效提高发生水平偏移时的系统稳定性以及 副边线圈的电压增益和传输效率。同时搭建了基于信号发生器的实验验证平台,实验结果表明,改 变线圈半径消除了频率分叉现象。
Abstract:
The existence of the compensation capacitor in the magnetic coupling inductive wireless power transfer system causes multiple resonance frequencies when the two coils move laterally or vertically, which results in the frequency conversion controller failing to identify the optimal frequency,and thereby affecting system stability. In order to solve this problem,based on the existing mutual inductance formula of coaxial coil,the mutual inductance formula of the lateral moving coil was established according to the Neumann formula. The relationship between the factors such as coil radius and lateral displacement and the mutual inductance was analyzed. Theoretical analysis shows that increasing the radius of the primary coil and lateral movement of coils can eliminate the frequency bifurcation phenomenon,and improve the system stability when the lateral movement occurs. And the voltage gain and transfer efficiency of the secondary coil are also improved. Besides,an experimental platform based on signal generator was built. The experimental results show that changing the coil radius eliminates the frequency bifurcation phenomenon.?
