Abstract: The structure of the transmitting and receiving coil in inductively coupled power transfer (ICPT) systems has a significant impact on the system’s performance. To develop a more flexible coil structure, we theoretically analyzed the impedance variations in high-frequency coil mutual inductance circuits and proposed the concept of a coil coupling body (CCB). By using two coils with mutual inductance, a combined CCB was constructed. The CCB can function as an independent coil and its values of L , C , and R can be modified by adjusting the mutual inductance coefficient between the coils in the coupling body. Using the CCBs as the primary and secondary sides of the system, a novel inductive wireless power transfer system was established. Also, by adjusting the mutual inductance, the impedance and resonance state of both the primary and secondary sides can be modified. Preliminary experimental studies show that the inductive power transmission system constructed with CCB not only facilitates tuning, but also exhibits good anti-offset performance.
