摘　　要：本文提出一种非线性直流电路故障诊断的有效算法。交替进行对故障电路的测试和计算该测试条件下标称电路的端口输出,采用优化搜索能很快找到屏蔽故障支路的特定激励。检查标称电路相应于该激励的支路响应,即能定位故障。An efficient algorithm for fault diagnosis of nonlinear d.c. circuits is presented in this paper. Special excitation which screens the faulty branch can be found rapidly by using optimization method. In this method, the test to malfunction circuits and the calculation for the output at nominal circuits port are made alternately. By checking the response of the branches in nominal circuits to the special excitation, the fault can be located.
