有源单口网络等效电源参数一次计算方法

Equivalent Power Calculation of Active Single-port Network Parameters

等效电源定理是计算网络响应的常用方法,在应用此定理分析电路时,求解等效电源的参数一般要进行两次计算得到,对于较复杂的有源单口网络计算工作量较大。研究证明,采用加源法一次可以计算出等效电源的开路电压和内阻或短路电流和内导,这减少了计算工作量,尤其对含有受控源的有源单口网络的等效电源参数计算更为简便。

The theorem of equivalent power network response is a common method of calculation;this theorem can simplify network analysis and calculations.But for the more complex single-port active network,the workload of computing is larger.The the-oretical studies have proved that by adding a source method can calculate the equivalent power of the open circuit voltage and short circuit current and internal resistance or conductance,this method reduces the computational workload,particularly to the calculation of equivalent power parameters with controlled source of the active single-port network.
