Wireless power transfer (WPT) systems can be used in various situations such as electric vehicles and electronic equipments. This paper developed a mobile WPT system with a LCCL resonance structure and a parameter configuration method to develop favorable transmission characteristics. Using the circuit equivalence principle, the formula for output power and transmission efficiency of the system was obtained. The system parameters were determined and the transmission characteristics the system were analyzed by simulation. The experimental platform was built according to the determined parameters and was used to analyze the transmission characteristics of the system. The experimental results show that the developed system can acquire favorable transmission characteristics and provide an effective means for 1.5 kW WPT application.
