The proposed IPT system uses series-series (S-S) and series-inductor-capacitor-inductor (S-LCL) compensation. In both compensation configurations, the rectifier operates in half-bridge (HB) and full-bridge (FB) modes. By using the correct switching pattern between compensation networks and the rectifier, four transfer power-coupling coefficient (P-k) curves are created. A 400 W prototype simulated in MATLAB demonstrates that, with the proposed method, output power fluctuation is limited to only 3% for coupling coefficients varying from 0.1 to 0.4, with system efficiency ranging from 80% to 95.9%. Compared to other methods, the proposed structure provides stable power transfer over an ultra-wide coupling variation and does not require special coil design, clamp circuit design, or complex control</span><span new="" roman="" style="font-family:" times="">.</span></span> Inductive Power Transfer (IPT), transfer power-coupling coefficient (P-k), Misalignment Tolerance, Power Fluctuation, Coupling Variation. 142 152 http://ijeee.iust.ac.ir/browse.php?a_code=A-10-5217-1&slc_lang=en&sid=1 Mostafa Jalalian-Ebrahimi m.jalalian_e@birjand.ac.ir 1800319475328460016043 1800319475328460016043 No Faculty of Electrical Engineering and Computer, University of Birjand, Birjand, South of Khorasan, Iran.
