本研究解决感应电能传输系统中的磁能最小化问题，以抑制磁场强度并制定磁能的最低边界。理论分析表明，磁场能量的最小值仅是耦合系数、接收机品质因数和发射功率的函数，在线圈及其耦合均为理想的情况下，磁场能量的最小值收敛于0。电磁仿真验证了磁场强度的抑制效果，通过磁场能量最小化，并显示相当小的损失，在传输效率。
This study solves the magnetic energy minimization problem in inductive power-transfer systems to suppress the magnetic field intensity and formulate the lowest boundary of the magnetic energy. The theoretical analysis shows that the minimum value of the magnetic energy is a function only of the coupling coefficient, quality factor of a receiver, and transmitting power and it converges to 0 under the condition that the coils and their coupling are ideal. The electromagnetic simulations verify the suppression effects of the magnetic field intensity by magnetic energy minimization and show quite a small loss in the transfer efficiency.
