This thesis aims to develop a wireless power transfer system (WPT) with constant voltage output using series-series parallel (S-SP) compensation topology. In order to achieve the goal of improving the dynamic performance and control accuracy of the system, the feedback control method is to optimize the parameters of the fuzzy proportional-integral-derivative controller with particle swarm algorithm in offline state. The parameters of the PID controller are optimized and adjusted online by the fuzzy control rules, and the feedback control is performed to implement the Phase-Shifted Control method, so that the system output can achieve the system target constant voltage output under the condition of fixed load or variable load. This paper firstly conducts numerical analysis and comparison of the characteristics of the induction coil circuit model and the resonance compensation circuit, derives the relevant formulas and then proposes the detailed system parameter design process of the overall system software and hardware. In order to verify the feasibility of the system proposed in this paper, we will carry out the actual measurement of circuit waveforms at all levels, and compare the output stability of three different control methods. The experimental results show that the system under the condition of load fluctuation. The fuzzy PID controller optimized by particle swarm optimization has the best stability and dynamic performance, so the research results of this paper can be used as a reference for the development of wireless power transmission systems.
