中文摘要:
      节点电压法是常用的电路系统分析方法之一,但当电路有短路线,并且短路电流是受控源控制量时,无法利用传统的节 点电压方程的标准形式正确求解这类电路。讨论并分析了这类问题,得出在不改变电路原有网络拓扑结构的情况下,只有把 短路电流(即控制电流)当作电流源时,才能得出正确的结果,并且给出了这种情况下合理的解释。该解释扩展了用节点电压 法的标准形式求解电路的应用范围,完善了节点电压法通用的求解形式,更有利于以后的教学。
英文摘要:
      The node voltage method is one of the commonly used circuit system analysis methods, but when short circuit occurs in the circuit and the short-circuit current is the control quantity of the controlled source, it is not possible to correctly solve such circuits using the standard form of the traditional nodal voltage equation. This paper discusses and analyzes such issues, and it is concluded that the correct result can only be obtained if the short-circuit current (the control current) is used as the current source without changing the circuit structure. And a reasonable explanation is given for this situation. This interpretation expands the application range of the circuit solution through standard form of the node voltage method, and improves the general solution form of the node voltage method, being more helpful to the future class teaching.
