efzauner Posted March 1, 2020 Share Posted March 1, 2020 The models seem to be using inductors as a voltage divider elements and not as any transformer where the voltage out/in is a function of turns ratio. I believe you have been implying turns ratio into the inductance values. This link uses inductor K coupling factor to create autotransformer models. Some good info here! http://www.beigebag.com/case_tapped_inductor.htm As for phase shift... if you write the inductor model as jwL and use voltage divider math Vout/Vin = jwL2/(jwL1+jwL2) the jw cancels out so you do not have any phase change... This makes intuitive sense as well since if use 2 identical inductors the magnitude of the voltage phasors Vout has to be half of Vin. KVL would not work if the phases of Vin and Vout arent the same.. Am I making sense? E Quote Link to comment Share on other sites More sharing options...
