摘　　要：在电池充电中,感应电能传输(inductive power transfer,IPT)系统通常需要实现恒流(constant current,CC)和恒压(constant voltage,CV)输出。同时,IPT系统的线圈偏移是难以避免的,因此系统同时需要具有抗偏移能力。文中提出一种基于混合钳位拓扑的IPT系统,利用钳位电路实现CC到CV的自动切换,通过四线圈结构的混合拓扑提高系统的抗偏移性能,简化系统控制复杂性。最后,搭建一个400 W的原理样机,验证所提方法的正确性和有效性。负载在5~100Ω范围变化时,系统在X轴方向偏移达52.5%和Z轴方向偏移为17.5%的情况下,CC模式下的输出电流和CV模式下的输出电压波动始终小于5%。In battery charging,inductive power transfer(IPT)systems typically need to achieve constant current(CC)and constant voltage(CV)outputs.At the same time,coil misalignment is often unavoidable in IPT systems,so the system also needs to have anti-misalignment capability.This paper proposes an IPT system based on a hybrid and clamp topology.The proposed method uses a clamp circuit to achieve automatic switching from CC to CV,and the hybrid topology of a four-coil structure is used to improve the system's anti-misalignment performance,simplifying the system control complexity.Finally,a 400 W prototype is built to verify the correctness and effectiveness of the proposed method.When the load varies in the range of 5~100Ωand the misalignment reaches 52.5%in the X-axis direction and 17.5%in the Z-axis direction,the fluctuations of output current in CC mode and the output voltage in CV mode are always less than 5%.
