交流包络调制无线电能传输系统的负载稳压输出研究

摘要

In order to achieve voltage regulation of wireless power transfer (WPT) system based on AC envelope modulation, according to the impulse theorem and the energy conservation principle,energy inj ection mode combined with free oscillation mode were used.The energy scale of primary part is adj usted to adapt for the changes of load,therefore,the output voltage regulation is realized.Simulation and experimental results illustrate that the output voltage of system keeps constantly in a dynamic load switch period.%为了实现交流包络调制无线电能传输系统的输出电压稳定，基于冲量定理与能量守恒原理，在初级侧采用能量注入与自由振荡模态组合的形式，调整注入初级回路的能量规模以适应负载的功率变化，从而实现动态负载条件下输出端的稳压。仿真与实验结果验证了在系统负载切换时，系统输出交流电压保持恒定。
