Aiming at the problems of the existing magnetic couplers used by wireless charging system (WCS) with multiple power transfer channels, this study presents an investigation into the use of magnetic integration technique and orthogonal decoupling method to design an orthogonal laminated magnetic integrated coupler with SDDD-MIOC (square, Double D (DD), and magnetic integrated overlap coils). Firstly, the concept of SDDD-MIOC is proposed to solve the key issues of the existing magnetic couplers. Then, the operating principle and design method of the proposed SDDD-MIOC are illustrated. Secondly, the coupling performance and electric characteristics of the designed magnetic integrated coupler with SDDD-MIOC are analysed in-depth. Finally, both experimental and simulation results verify that the designed magnetic integrated coupler with SDDD-MIOC helps the WCS with three power transfer channels to achieve the low component voltage or current stress, high space utilisation, good power expansion ability, and high system fault-tolerant ability.
