Abstract

Inductive Power Transfer (IPT) system is an appealing approach among researchers as well as industrial manufacturers of electric vehicle (EV) charging systems. IPT can be used to transfer power through the air gap by generating a high-frequency current in the transmitter pad and inducing current magnetically in the receiver pad. A triple quadrature pad (TQP) has been proposed to enhance transferred power in larger misalignments and various air gaps. This pad excels in its previous three-coil structures by implementing a fewer number of inverters and lower dimensions compared to other similar structures. All these features result in a higher coupling coefficient in low misalignments and higher tolerance to misalignment in horizontal displacements. A laboratory-scale prototype has been designed and built for 26 kHz switching frequency and 150 mm air gap in order to deliver maximum power in different displacements. Simulations have been done by the finite element analysis (FEA) tool of ANSYS Maxwell. The prototype has been built to validate the simulation results.

用于电动汽车无线电力传输系统的三正交焊盘的研究

Ali Mosallanejad，伊朗德黑兰Shahid Beheshti大学电气工程系。电子邮件：a_mosallanejad@sbu.ac.ir摘要感应功率传输（IPT）系统在电动汽车（EV）充电系统的研究人员和工业制造商中是一种很有吸引力的方法。IPT可用于通过在发射器焊盘中产生高频电流并在接收器焊盘中磁感应电流来通过气隙传输功率。已经提出了一种三正交焊盘（TQP），以在较大的未对准和各种气隙中增强传输功率。与其他类似结构相比，该焊盘在以前的三线圈结构中表现出色，实现了更少的逆变器数量和更低的尺寸。所有这些特征导致在低未对准情况下具有更高的耦合系数，并导致对水平位移中的未对准具有更高公差。为了在不同的位移中提供最大功率，已经设计并建造了一个实验室规模的原型，其开关频率为26 kHz，气隙为150 mm。利用ANSYS Maxwell有限元分析工具进行了仿真。已经建立了原型来验证仿真结果。
