Research and optimization of Transmission Characteristics of Magnetic Coupled Resonant Wireless Charging System

Research the transmission efficiency optimization problem of magnetic coupling resonant wireless charging system. According to the transmission principle of resonant wireless charging, the system multi-parameter matching problem is optimized to make the wireless charging system work in the best state. Construct an equivalent model of series-series compensation topology, and obtain three key parameters that affect the transmission efficiency of the system: frequency, distance and load resistance. Using the particle swarm optimization algorithm with compression factor, the best of the three key parameters is obtained. The matching value, compared with the system that only optimizes two key parameters, proves that this method can find the best matching value between the parameters faster and more accurately within the set feasible range, and the system transmission efficiency reaches Optimal. The effectiveness of the algorithm and the correctness of the analysis process are verified by a Matlab simulation example.
