“…Ahn and Hong [9] claimed that the resonant frequency is changed and the system transfer efficiency also decreases due to the mutual inductance between two receiver coils. Woronowicz et al [10] proposed an IPT system design based on all the combinations of secondary-side compensation to ignore the effect of mutual inductance between the secondaries on IPT system. Fu et al [11] proved that adding capacitive reactance could suppress the influence of mutual inductance between two receiver coils.…”

In the bipolar (multiple) receiver inductive power transfer (IPT) system, the delivered power sharply drops with detuning due to the coupling between the two receiver coils. As a remedy to this problem, a new self-decoupled model of bipolar receiver by adding decoupling coils (sub-coils) to the receiver coils is proposed. First, the IPT system topology with a bipolar receiver has been analysed. Then, the self-decoupled model of bipolar receiver has been built. Furthermore, a quantitative calculation model of decoupling coils has been given. Finally, a series of IPT system comparison experiments for a single receiver, a bipolar receiver, and the decoupled bipolar receivers by using overlap, and the presented method are carried out separately. The results show that the presented self-decoupled model of bipolar receiver can effectively overcome the electromagnetic coupling between the dual receiver coils on the system resonance. The results further verified that the presented model is also suitable for the case with core plates.
