正弦稳态电路中求解最大功率传输问题的方法

Solution to the Maximum Power Transmission Question in Thesine Stable State Circuit

在正弦稳态电路中,当负载阻抗与电源内阻抗为共轭匹配时负载获得最大功率传输.为求解电源内阻抗需要利用戴维南定理对电路进行等效变换.详细介绍了戴维南定理求解含源单口网络的开路电压U_α和等效阻抗Z_o方法.

The load obtains the maximum power transmission when loaded impedance and power source internal resistance for conjugate match in sine stable state electric circuit. In order to solve the pow- er source einternal resistance, the equivalent transformation in the electric circuit is made with Thevenin＇s Theorem. With an application of Thevenin＇s Theorem, a solution to the open-circuit voltage Uoc of an active single port network and the equivalent resistance Zo is given in this article.
