【Abstract】 This paper describes the research on the analysis method of analog circuit DC and the development of an analog circuitfault diagnosis training system which can systematically use improved DC accompanying model,do linear transformation for the nonlinearcomponents,set up linear circuit equations by means of the node voltage method,and get numerical solution of the circuit equationsby-means of iterative algorithm. Simulation results show that the system can simulate the hard fault of analog circuit. Expanding applicationwithin the small scope shows that the system can quickly,effectively cultivate analog circuit fault diagnosis skills for electrical specialtystudents.更多还原
