prob. 11.1(e); Lp =0; does Re become 0? which means j1 and j2 = infinity?
Hello everyone, In prob. 11.1(e); Lp =0; Does that allow us to make Re = 0 as it has Lp in its Numerator ? Making Re=0 would make j1 and j2 = infinity as they have Re in their denominator. Any comments would be useful. Thanks, Nitish
After discussion with Prof. Maksimovic, I realized I need to state this more clearly. We cannot set L = zero in all coefficients and other parameters and elements dependent on L because the converter won't work without L. The only place we are setting L=0 is where the element L is present in the small signal model, so that we neglect the dynamics caused by it.
I guess we should leave the various parameters in L unchanged, as done in the buck converter example in class (lecture 18).
