This paper presents a topology of integrated on-board charging system with separated inductors on grid side. It employs the on-board three-phase electric power converter in time-division multiplexing, and separates the grid side inductors from the vehicle, reducing volume, weight and cost of the on-board charging system. To provide an accurate inductance for the control system, a data-driven inductance identification method is proposed. The inductance is first identified at the uncontrolled rectification stage, then the real-time online inductance correction is further implemented at the PWM rectification stage. In addition, the operating principle and structural characteristics of the proposed topology are discussed, and the inductance identification method is analyzed in detail. Finally, a 2 kW experimental prototype is built to validate the correctness of the theoretical analysis and effectiveness of the proposed identification method applied to the proposed topology in this paper.

基于电机驱动器的集成车载充电系统拓扑和数据驱动电感识别方法

本文提出了一种在电网侧具有分离电感的集成车载充电系统的拓扑结构。它采用车载三相电力变换器进行时分复用，将电网侧电感与车辆分离，减少车载充电系统的体积、重量和成本。为了给控制系统提供准确的电感，提出了一种数据驱动的电感识别方法。在非受控整流阶段首先识别电感，然后在PWM整流阶段进一步实现实时在线电感校正。此外，讨论了所提出拓扑的工作原理和结构特点，并对电感识别方法进行了详细分析。最后，
