摘　　要：斩波控制在电力机车牵引控制系统中与四象限控制相互配合,在抑制中间直流母线电压的突升方面起至关重要的作用。在此基于电力机车的主拓扑结构,对所提比例积分(PI)控制的斩波原理进行了分析,并与传统斩波控制方式进行了对比,分析了斩波控制与不同工况下四象限的运行关系,最后通过实验对所提斩波控制策略应用的控制性能进行了验证。The chopper control cooperates with the four quadrant control in the traction control system of the electric locomotive,and plays a vital role in inhibiting the sudden rise of the intermediate direct current bus voltage.Based on the main topology of electric locomotive,the proposed chopping principle of proportional integral(PI)control is analyzed compared with the traditional chopper control method.The operation relationship between chopper control and four quadrants under different working conditions is analyzed.Finally,the control performance of the chopper control strategy proposed is verified by experiments.
