摘要
文章主要从磁耦合谐振原理出发,通过对电动汽车的使用环境考量而设计出的电动车用磁耦合谐振式无线充电系统的教学演示模型。在通过对系统的发射端、接收端、数据收集部分进行设计与分析,可实现直接将220V的系统电源,通过磁耦合谐振效应传递到负载,最终在接收端接收能量。系统最终可在传输距离为10cm的情况下,实现1kW功率的传输,并可通过显示屏直观演示功率效率变化情况等。
In this paper,based on the principle of magnetic coupling resonance,the teaching demonstration model of the magnetic coupling resonant wireless charging system for electric vehicles is designed by considering the use environment of electric vehicles.By designing and analyzing the transmitting end,receiving end and data collecting part of the system,it is possible to directly transfer the 220V system power to the load through the magnetic coupling resonance effect,and finally receive the energy at the receiving end.The system can finally realize the transmission of 1 kW power with a transmission distance of 10 cm,and can visually demonstrate the change of power efficiency through the display screen.
