本文通过简单的例子,研究了代文宁定理在具有受控源电路中的应用。采用受控源转移的方法,解决了应用代文宁定理时,失去受控量的困难,并推广到一般情况。说明只要把受控量加以变换,一般含有受控源的网络是可以应用代文宁定理的。 In this paper, through a simple example, we study the application of the Dai-Wen-Ning theorem in a controlled source circuit. By using the method of controlled source transfer, the difficulty of losing the controlled quantity when applying the Sven-Wenning theorem is solved and generalized to the general situation. Explain that as long as the controlled amount to be transformed, generally contains the controlled source network is the application of the Wenning’s theorem.
