摘　　要：滞环电流控制方法是电力电子及电力传动中应用最多的控制方案之一。以往对这种方法的分析忽略了延时等非理想环节的影响,因而存在一定的误差。详细分析了考虑延时的滞环电流控制物理过程,以及延迟环节、环宽、电流改变量、开关频率等关键参数之间的定量关系,揭示了其内在规律。通过试验验证了理论分析与计算方法的正确性。Hysteresis current control method play an important role in power electronics and power transmission. Research in detail on hysteresis current control taking delay link into account, which was always ignored in traditional analysis, was proposed in this paper. The physical process of hysteresis current control and relationship along key parameters such as hysteresis band, inductance and switching frequency were revealed. Experiment has been carried out to prove the analysis.
