摘要
无线电能传输在实际应用中的关键性问题是系统的传输效率和负载电压的稳定。综合考虑线圈谐振频率、耦合系数、负载阻抗、电源内阻,应用互感耦合理论分析了系统传输效率和电压增益与耦合系数和负载电阻的关系。对比了四种常见的无线传能系统闭环控制方法,并提出最高效率点控制策略,保证系统效率最大化同时调节负载输出电压。
The critical problem of wireless power transmission in practical application is the transmission efficiency of the system and the stability of the load voltage. Application of mutual inductance coupling theory analysis the relationship between the system transmission efficiency or the voltage gain and the coupling coefficient or the load resistance,considering the resonant frequency of coil and coupling factor, load impedance, the internal resistance of the power supply. Compared with the closed-loop control meth- ods of three common wireless transmission systems.Furthermore,a maximum efficiency point tracking control scheme is proposed to maximize the system efficiency while regulating the output voltage.
