电路课程中含受控源电路教学的探讨

Study on Teaching of Electric Circuit with Controlled Sources

含受控源的电路在“电路”课程教学中既是难点又是重点。本文根据该课程的实际教学经验总结了含受控源电路的分析方法———基本分析方法(支路法、回路法、节点法和戴维南定理)和受控源等效变换法(受控源等效为电阻或电压源与电阻的串联组合),结合一些具体实例对每一种方法做了详细的分析,总结了含受控源电路的教学特点,并对这两种分析法进行了比较,为含受控源电路的教学提供了有益的建议。

Electric circuit with controlled sources is both an emphasis and a nodus in teaching of Electric Circuit Theory. Analysis method of electric circuit with controlled sources including basic analysis method （i. e. by means of branch current method, loop current method, node voltage method and Thevenin＇s Theorem） and equivalent conversion method （i. e. controlled source is equivalent to a resistance or a voltage source series connected with a resistance） are summarized according to teaching experience. And the two kinds of methods are studied and compared with some examples. Discussion results are helpful to the teaching of electric circuit with controlled sources.
