Abstract

Wireless power transfer (WPT) can improve power supply safety, reliability and flexibility. Multi-receiver WPT systems have many advantages as high power, contactless power supplies for electric vehicle charging, rail transit and other systems. However, dynamic analysis and optimization methods are not well developed for multi-receiver WPT systems. This paper presents a dynamic model for a typical multi-receiver WPT system to analyze the effects of the system parameters on the steady-state and dynamic responses. Then, a multi-objective parameter optimization method is developed for the system based on the dynamic model. Simulations and experiments show that the dynamic model and optimization method are accurate and effective.
