LTspice tutorial - Modeling transformers

#102 #ltspice In this video I look at how a basic transformer can be modeled in LTspice and what are the common simulation particularities to watch out for. Afterwards, I perform some measurements on a practical transformer and try to implement that. Finally I look at some datasheets to see just what sort of parameters are commonly available.
