Advanced magnetic design was proposed in this study, considering all the detailed dimensions of the construction of the transmit and receive pads, after a detailed study was made in the (Ansoft Maxwell) program of the effect of all dimensions of the pad components on mutual inductance, coupling coefficient and self-inductance. For both pads to get the best coupling suitable for DWPT applications. It is characterized by its high tolerance of misalignment to increase the distance between the transmitter pads, which is due to the reduction in the number of transmitter pads and the lengthening of the loading passages. This is in addition to proposing steps to design a DWPT system based on the LCC-LCC compensation network.The system based on these proposed steps is characterized by the fact that it works where the power transmission and the efficiency are best, even with the occurrence of misalignment cases. This study and the proposed design steps were directed to the design of a DWPT system that delivers power from the first level, P = 3.7 kW, to a distance from the second level, Z = 150 mm, with an efficiency of not less than 85%, with cases of misalignment.Theoretical and simulation results showed a very large convergence, which proves the correctness of the proposed steps, since an efficiency between (98% and 88%) was achieved for the best case and the worst case of misalignment and a misalignment tolerance that achieves more than 62% of the length of the pad. A practical model was built for the transmitting and receiving pads, and the practical results were compared with the simulation results of the program (Ansoft Maxwell), in addition to the practical construction of the whole system after simulating it with the real available practical values in the laboratory and comparison of practice and simulation results to ensure the correctness of the proposed steps and to ensure the power can be transmitted wirelessly.
