Study on IPT Charging Systems With the Characteristics of Misalignment Tolerant in 2-dimension Plane and Constant Voltage Output

  • 摘要: 为了降低感应电能传输(inductive power transfer,IPT)充电系统反馈控制的复杂性,增强系统耦合机构抗偏移能力的同时保证系统恒压(constant voltage,CV)输出,该文基于LCC-S与S-LCC拓扑电路特性提出LCC-S与S-LCC混合拓扑电路并分析其抗偏移恒压输出特性;选取double-D quadrature(DDQ)结构线圈作为耦合机构,并提出抗偏移参数设计方法,以实现系统二维平面抗偏移恒压输出。此外,该方法还具有以下明显优点:无需复杂的反馈控制,几乎没有无功输入。最后,该文搭建1k W系统原理样机,在横向和垂向考察抗偏移恒压输出特性。负载在45~120Ω范围内变化时,系统输出电压波动始终介于设定的5%以内,在选定的线圈参数条件下,线圈横向最大偏移50%,而线圈在垂向最多可减小23.33%。实验结果表明该方法有效且可行。

     

    Abstract: In order to reduce the complexity of the inductive power transfer(IPT) charging systems with feedback control schemes, and to enhance the misalignment tolerant of the magnetic coupler, as well as to guarantee the constant voltage(CV) output of the system, a hybrid topology circuit based on the characteristics of LCC-S and S-LCC topologies was proposed in this paper. The characteristics of misalignment and CV output of the hybrid topology were analyzed. Then, to realize the IPT systems with CV output and misalignment tolerant in 2-dimension plane, the double-D quadrature(DDQ) pad was selected as the magnetic coupler, and a parameter design method was proposed. In addition, the proposed methods are with the following advantages: no complex feedback control schemes and almost no reactive input. An experimental prototype of 1 kW system was constructed to verify the effectiveness and feasibility of the proposed method, showing the characteristics of misalignment tolerant in lateral and vertical directions. The fluctuation of the output voltage is within the requirement of 5% with the load varying from 45Ωto 120Ω, and under the condition of the selected coil parameters, the maximum misalignment in lateral direction is 50%. Besides, the maximum misalignment in vertical direction can reduce up to 23.33%. The experimental results show that the proposed methods are effective and feasible.
