一种被广泛采用的电路教材曾指出:在线性网络分析中,受控源支路不可以被替代,国内外其它一些有影响的电路著作对此亦没有明确讨论。这些著作几乎无例外地指出:在叠加原理和等效电源定理中,受控源和独立源起着不同的作用,于是采用了不同的处理方法。本文以待定的独立激励替代线性受控激励,考虑到列写电路方程可将受控源按独立源对待,从而得到叠加法和等效电源法中也可以采用同样的处理方法,其适用范围不受影响。
A widely used circuit teaching material has pointed out: In the linear network analysis, the controlled source branch can not be replaced, other influential circuit books at home and abroad are also not specifically discussed. Almost without exception, these works point out that in the superposition principle and the equivalent power theorem, the controlled source and the independent source play different roles, so different approaches are taken. In this paper, to be determined by the independent incentive instead of linearly controlled excitation, taking into account the column write circuit equations can be controlled source according to an independent source, resulting in superposition method and equivalent power law can also be used in the same treatment method, the scope of application is not Affected.
