Coupler parameters, such as transmitter inductance ( L_Tx ), receiver inductance ( L_Rx ), and the coupling coefficient ( k ) or mutual inductance ( M ), vary with the misalignments. Their variations must be quantified and incorporated into the design and optimization stage as they impact performance indices such as efficiency and leakage magnetic field. Most of the solutions proposed in the literature compromise the performance of the coupler in search of a misalignment-tolerant design. Therefore, this article presents a method to incorporate the misalignments into the design and optimization process of an inductive power transfer (IPT) coupler by utilizing robust optimization, where misalignments are considered as noises or disturbances or uncertainties to a perfectly aligned coupler. The optimized designs resulting from this method will not compromise the performance of the coupler in search of a misalignment-tolerant design. Effectiveness of the proposed robust optimization method is experimentally verified with a 3.7 kW hardware prototype.

感应功率传输耦合器设计中失准容差的鲁棒优化

耦合器参数，例如发射器电感（ L _Tx ), 接收器电感 ( L _Rx ) 和耦合系数 ( k ) 或互感 ( M )，随不对中而变化。它们的变化必须量化并纳入设计和优化阶段，因为它们会影响效率和漏磁场等性能指标。文献中提出的大多数解决方案都会损害耦合器的性能，以寻求偏差容忍设计。因此，本文提出了一种通过利用鲁棒优化将不对中纳入感应功率传输 (IPT) 耦合器的设计和优化过程的方法，其中不对中被视为完美对齐耦合器的噪声或干扰或不确定性。通过该方法得到的优化设计不会损害耦合器在寻求偏差容忍设计时的性能。所提出的鲁棒优化方法的有效性通过 3.7 kW 硬件原型进行了实验验证。
