兼顾抗旋转偏移和中心磁场抑制的三相IPT系统设计与分析
Design and Analysis of Three-phase IPT System with Anti-rotation Misalignment and Central Magnetic Field Suppression
摘要
Abstract
Compared with the traditional plug-in charging method,it is safer and more convenient to employ an inductive power transfer(IPT)system to charge autonomous underwater vehicles(AUVs).To alleviate the strong magnetic field inside the AUV hull and the dramatic power fluctuation caused by the rotation misalignment of the AUV under the turbulent water,a three-phase IPT system with a novel coupling structure is proposed.The coupler is composed of three transmitting coils and four receiving coils connected in alternating reverse series,which can suppress the central magnetic field and improve the anti-rotation misalignment performance simultaneously.The Maxwell simulation results show that when the AUV hull rotates,the equivalent mutual inductance Meq fluctuation is less than 2%,and the magnetic field of the AUV center always maintains a low level.In addition,to simplify the system analysis,a decoupling method based on a passive component is adopted to decouple the three transmitting coils.A laboratory-scale prototype based on an LCC-S compensation topology was built to verify the feasibility of the system.Experimental results show that when AUV rotated,the output power varied from 536 W to 595 W with a maximum fluctuation of 9.91%.The maximum DC-DC efficiency of the system was 86.28%.关键词
