摘要：

The transmission efficiency and output power of wireless power transmission systems with three coils are greatly affected by the distance between the coils, the coil turns, the coil size, and the working frequency. In specific three-coil systems, the transmission efficiency and output power of the system cannot reach the maximum value at the same time. To solve the above problems, in this paper, the variables were taken as optimization ones, including the coil turns, the side length of the central turn, the system frequency, the distance between the transmitter coil and the relay coil, and the distance between the relay coil and the receiver coil. The product of efficiency and output power was constructed as the objective function. Genetic algorithm was used to obtain the compromise between the efficiency and the output power, and the system parameters with nonlinear constraints were optimized. Finally, the simulation and experiment verify the correctness of the optimization results. The designed system has a transmission distance of 37. 39 cm, an output power of 151. 37 W, and a system efficiency of 81. 02%, which meets the actual application requirements. © 2023 Editorial Department of Electric Machines and Control.
