| 摘 要： | 提出了一种基于AC-link的新型电机驱动充电一体化拓扑结构,可以满足电机驱动控制和充电两种工作模式。该拓扑正向工作时驱动电机为电机驱动控制状态、反向工作时给蓄电池充电为充电状态。首先对该新型拓扑结构两种工作模式的工作原理进行详细介绍,采用有效的控制策略并使用Simulink软件搭建仿真模型,对一体化拓扑结构和控制策略进行验证,仿真结果表明,该拓扑工作在充电模式时可以满足电池全部充电阶段的不同电压需求;工作于电机驱动模式,无论是加速过程还是正常工作过程,定子电流均呈现良好的三相正弦形态,并且转速可以达到给定值,从而证明了这种拓扑结构和控制策略的可行性。

| Abstract: | This paper proposes a novel motor-driving charging integrated topology with high-frequency AC link (HF AC-link), soft-switching operation and high-frequency (HF) galvanic isolation, which can apply to the two modes of motor driving control and charging. The topology belongs to a new class of resonant AC-link topology, and its link is composed of a series ac inductor/capacitor (LC) pair.When the topology is working in the forward direction, the driving motor is in the motor driving control state, and the battery is being charged in the backward working period. In this paper, the principle of operation of the two working modes of the new topology is introduced in detail. The effective control strategy is used and the simulation model is built by MATLAB/Simulink software. The integrated topology and control strategy are verified. The simulation results show that the topology works. The charging mode can meet the different voltage requirements of the whole charging phase of the battery; working in the motor driving mode, the stator current exhibits a good three-phase sinusoidal shape in both the acceleration process and the normal working process, and the rotation speed can reach a given value, thereby proving the feasibility of this topology and control strategy. |
