摘　　要：本文详细介绍了有源网络Y-△等效变换的方法,利用开路短路法、等效电路法两种方法推导出等效变换的解析表达式,阐明Y型有源网络与△型有源网络等效变换均具有无穷多解的特点。文章从理论上解释了无穷多解存在的原因,并利用Multisim仿真验证了等效变换方法,结论表明等效变换方法在正弦交流稳态电路分析中同样适用。This paper introduces an effective Y-△transformation of active networks based on the analytic expression of equivalent transformation inferable from open circuit short circuit method or equivalent circuit method.We theoretically explains the reason why the equivalent transformations of both△type and Y type of active networks have infinitely solutions.Furthermore,Multisim simulation is utilized to test and verify the equivalent transformation method,which proves that the method can also be used in steady state analysis of sinusoidal AC.
