Abstract

In this work, we propose two-degree-of-freedom coils for a high coupling wireless power transfer (WPT) system to achieve a constant efficiency against rotation and linear movements. The transmitting (Tx) coil and receiving (Rx) coil were wound on a cylindrical joint structure. The Rx coil has a linear motion (∆) between three assumed positions, as follows. Lower position (P₁), middle position (P₀) and an upper position (P₂). Besides, the Rx coil has an angular movement (α) around its axis between 0^◦ and 360^◦. The mutual inductance (M) between the Tx and Rx coils is derived and validated by calculations and simulations. Design procedures of the WPT coils and analytical investigations for maximizing the power transfer efficiency are discussed in detail. In addition, simulation results under linear and angular movements are presented. Finally, the WPT coils were fabricated. The experiment results were in good agreement with the calculation and simulation results.
