基于正交DD线圈副边去耦合干扰的双负载无线电能传输系统
Double-load Wireless Power Transfer System with Secondary-side Interference Decoupling Based on Orthogonal DD Coil
摘要
Abstract
In a double-load wireless power transfer(WPT)system,the problem of coupling interference between sec-ondary-side coils becomes a critical factor that seriously limits the system performance.To solve this problem,a single-transmitter dual-receiver magnetic coupling mechanism is proposed,which aims to solve the problem of coupling inter-ference between two secondary-side coils.In addition,the same power output for both loads is achieved through the de-sign of the primary-side coil.Without using shielding materials or control methods,this mechanism can achieve complete decoupling of two secondary-side coils only through the design of coil structure.Experimental results show that the ener-gy transfer efficiency of the WPT system with this mechanism can achieve 88.7%under double-load.Moreover,the two loads can operate independently with no interference.关键词
