摘要
基于戴维宁定理等效电阻采用实验方法求解中,当开路电压为零,短路电流也为零时,戴维宁等效电阻不能用实验方法确定以及戴维宁等效电阻为复阻抗时,其相位不能用实验方法确定的两个问题,针对前者采用电路分析的常规方法解决了这一问题;对第二个问题则采用实验辅助手段,多次测量电压、电流并对这些测量结果进行理论分析计算,解决了等效电阻为复阻抗的相位确定问题。丰富了戴维宁等效电阻开路、短路法的实验求解。
Based on theorem Thevenin equivalent resistance the use of experimental methods to solve, when the open circuit voltage is zero, short-circuit current is zero, the Thevenin equivalent resistance can not be determined experimentally and the Thevenin equivalent resistance for the impedance, its phase can not be experimentally identified two issues, the former used conventional methods of circuit analysis to solve this problem; the second question is the use of test aids, multiple voltage, current measurements and theoretical analysis of these calculations, to solve the equivalent resistance for the impedance phase to determine the problem. This paper enriched Thevenin equivalent resistance open, short, experimental method to solve.
