中文摘要	冲击波形发生器广泛应用于电力电子设备的电磁兼容检测。其发生电路的设计一般先确定电路结构,再利用拉普拉斯变换推导出电路元器件与波形的关系。如变换电路结构时,则需重新推导相应的关系,增加了工作量。本文举出一种新的设计方法,提出一个通用曲线,且用最小二乘法对该曲线进行拟合,利用其确定波形的衰减系数和频率,再根据不同电路结构的不同参数关系得到元器件数值。这由通用到特殊的方式,提高了工作效率,使设计方法更系统。本文除介绍方法外,还给出了大部分发生电路的拉普拉斯变换公式,并在文中进行了设计举例。通过实例检验,该方法的设计结果完全满足IEC标准。; Surge generator has been widely applied to electromagnetic compatibility detection. Generally, the design of generate circuit is based on the following procedures. First, circuit structure is determined according to waveform. Then, the relationship between circuit parameters and wave is conducted from Laplace transform. Finally, values of circuit components are drawn. However, we have to conduct the relationship again when circuit structure is changed and workload inevitably increases. In this research, a new circuit design method was established. First, the modulus decay and frequency of waveform was determined by making use of a master curve. Second, circuit components values were drawn based on relationships between different parameters and circuit structures. This new method presented universal parts of different circuit structures and then calculated on selected circuits. Finally, the design efficiency is enhanced and workload is decreased. In this paper, the method is summarized in detail, polynomial fitting is carried through according to master curve, and the design process is finally improved by comparing the errors before and after the curve fitting. The design results are shown to be satisfied with IEC standards and correct illustrated by applying to practical examples.
