摘要
通过Multisim软件的Parameter Sweep参数扫描功能,探究了线性含源二端网络内部参数及外接负载变化情况下,负载获得功率的规律,并用图示方法展示了最大功率传输定理;探讨了其适用条件及误区,对最大功率传输定理的教学及应用有一定的指导意义。
In this paper, the rule of the maximum power acquisition is explored through the parameters scanning function of the Multisim software in the case of changing the internal parameters and external load of the two-terminal network of the linear source. The maximum power transfer theorem is shown by using graphic method. The applicable condition and the erroneous zone are discussed. It has certain guiding significance on teaching and application of the maximum power transfer theorem.
