This article presents an on-board charger for the electric vehicles (EVs) by integrating the drive-train components into the charging process. The stator windings of three-phase induction motor (IM) can be used as a grid interfacing inductor with the constraint that the rotor should be in the stationary position during the charging mode. This article proposes the stator winding configurations of three-phase IM split into two equal parts at zero electrical degree for the on-board integrated battery charger. The effective filtering with these two three-phase windings combination, either in series or parallel while the rotor is in a stationary position, is analyzed. The equivalent inductance provided by the stator windings for filtering is increased by generating the pulsating magnetic field (PMF) in the motor. However, it results in the unbalanced impedances in filter causing odd harmonics in the grid current. This is resolved by using a modified double synchronous reference frame control algorithm, which maintains the balanced current operation with the unity power factor at the grid interface during the charging mode. This configuration is obtained by using the existing three-phase-based drive-train components, thereby providing the saving in space and reducing the weight of EV. Experimental results for the proposed winding configurations are presented with filter losses and system efficiency.

使用三相感应电机定子绕组作为滤波器的电动汽车集成电池充电器

本文介绍了一种通过将传动系统组件集成到充电过程中的电动汽车 (EV) 车载充电器。三相感应电动机 (IM) 的定子绕组可用作电网接口电感器，但其约束条件是转子在充电模式期间应处于静止位置。本文提出了用于车载集成电池充电器的三相 IM 在零电度下分成两个相等部分的定子绕组配置。分析了在转子处于静止位置时串联或并联的这两个三相绕组组合的有效滤波。通过在电机中产生脉动磁场 (PMF) 来增加由定子绕组提供的用于滤波的等效电感。然而，它导致滤波器中的不平衡阻抗导致电网电流中的奇次谐波。这是通过使用改进的双同步参考系控制算法来解决的，该算法在充电模式期间保持电网接口处具有统一功率因数的平衡电流操作。这种配置是通过使用现有的基于三相的传动系统组件获得的，从而节省了空间并减轻了 EV 的重量。提出的绕组配置的实验结果与过滤器损耗和系统效率一起呈现。在充电模式期间，它在电网接口处以单位功率因数保持平衡电流操作。这种配置是通过使用现有的基于三相的传动系统组件获得的，从而节省了空间并减轻了 EV 的重量。提出的绕组配置的实验结果与过滤器损耗和系统效率一起呈现。在充电模式期间，它在电网接口处以单位功率因数保持平衡电流操作。这种配置是通过使用现有的基于三相的传动系统组件获得的，从而节省了空间并减轻了 EV 的重量。提出的绕组配置的实验结果与过滤器损耗和系统效率一起呈现。
