利用混合拓扑实现强抗偏移性能的紧凑型电动汽车无线充电系统

Misalignment-tolerant Compact Electric Vehicle Wireless Charging System by Using Hybrid Topology

  • 摘要: 电动汽车无线充电由于具有自动化、安全性和便利性等优势,得到广泛的研究。电动汽车无线充电技术上存在的障碍包括抗偏移性能的问题,基于LCC-S和S-S拓扑串联构成的混合补偿拓扑,提出一种新型的具有强抗偏移性能的紧凑型电动汽车无线充电系统。使用1套单极型线圈和1套田字形线圈作为2套拓扑的功率传输线圈,以提升电动汽车前进方向和车门到车门方向的抗偏移性能。原边的田字形线圈既作为功率传输线圈,又作为LCC-S拓扑中的补偿电感,实现紧凑和低成本的结构。所提系统实现2个方向的抗偏移性能。最后,通过实验验证所提方案的有效性。

     

    Abstract: Recent years have witnessed the booming development of electric vehicles (EVs). Wireless charging for EVs has been extensively studied due to its advantages of automation, safety, and convenience. One of the main obstacles facing EV wireless charging is misalignment tolerance. This paper proposed a novel misalignment tolerant compact EV wireless charging system based on the hybrid compensation topology, which was a series connection of the LCC-S and the S-S topologies. A set of unipolar coils and a set of quadrupole coils were employed as the power transmission coils of both topologies in the EV wireless charging system to improve misalignment tolerance on both the moving direction and the door-to-door direction. The primary quadrupole coil was utilized both as the transmitting coil and as the compensating inductor of the LCC-S topology, realizing a compact and low-cost structure. The proposed system achieved good misalignment tolerance on both directions. Experimental results validate the proposed wireless charging system.
