摘要
针对强磁耦合共振模式无线电能传输系统中输出控制问题,提出一种新型的原边控制方法。该方法通过检测发射线圈的电压电流来实时辨识共振线圈间互感和负载以及输出电压的变化,根据输入输出电压的关系设计Buck变换器以控制输出电压,克服了传统恒压控制需要2个控制器或者原副边需要无线通信的弊端,因此相对于传统的的恒压控制,此方法简化了系统的设计,提高了系统的可靠性。制作一个强磁耦合共振模式无线电能传输装置,通过实验验证了该辨识方法和控制方法的可行性。由于该方法可通过原边来得到副边的系统参数,因此通过原边即可对副边进行控制,在诸如生物体内供电等场合具有很好的应用前景。
For control problems of strong coupling magnetic resonance mode of wireless power transmission systems（SCMRWPT）,a new primary-side control technique was proposed.By detecting the transmitter coil voltage and current,the mutual inductance of the resonant coils,the system load and the output voltage were accurately identified,which overcome the drawbacks of traditional constant voltage control which requires two controllers or need wireless communication between the powering side and the receiving side.Compared with the traditional constant voltage control in wireless power transfer system,this technique simplifies the system design,improves system reliability.The feasibility of the identification and control technique was verified by experiment.The system parameters of the receiving side was got through the powering side,therefore,the output can be controlled through the primary side,and applications such as biomedical implants is expected to be the popular choice.
