摘要
无线电能传输系统在实际应用中,需要实现电能与信息的同时传输,适用于多种应用场景。文章在双全桥无线电能传输系统基础上,设计注入式信息传输方法,将高频信息载波注入电能回路,利用共享耦合通道实现无线电能与信息同时传输。建立双全桥无线电能传输系统模型,分析得到系统传输功率与原、副边移相角之间关系,分析信息反向传输特性,得到电能与信息传输优化方法。最后,通过实验验证所提出方法的可行性和有效性。
In the practical application,the radio cnergy transmission system needs to realize the simultancous transmission of electric energy and information,which is suitable for a variety of application scenarios.Based on the dual-bridge radio encrgy transmission system,the injcction information transmission method is designed to injcct the high-frcqucncy information carricr in-to the electric energy circuit,and realize the radio energy and information transmssion simulta-ncously by using the shared coupling channel.The model of the double full bridge radio energy transmission system is established,the relationship between the system transmission power and the original and secondary edge phase angles is analyzed,the reverse transmission characteristics are analyzed,and the optimization method of electric energy and information transmission is ob-tained.Finally,the feasibility and effectiveness of the proposed method are verified by experi-ments.
