摘要
为了解决目前全方向无线充电后端监测模式控制复杂、损耗大的问题,本文采用了一种锥形线圈排布方式,通过理论分析,提出了基于sepic电路的最大功率跟踪策略;在此基础上,进一步构建了基于自适应控制算法的负载位置前端监测系统,通过发射侧的信号采集,有效实现对负载位置的实时准确监测;最后设计了实验样机,验证了系统的可行性。
In order to solve the problem of complex control and large loss of monitoring mode of all-directional wireless charging back-end,this paper firstly designs a conical coil arrangement mode,and proposes the maximum power tracking(MPPT)strategy based on sepic circuit through theoretical analysis.On this basis,a front-end monitoring system of load position based on adaptive control algorithm is proposed.Through signal acquisition on the transmitting side,real-time and accurate monitoring of load position can be effectively realized.Finally,an experimental prototype is designed to verify the feasibility of the system.
