【Abstract】 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.更多还原
