HW #5 Solution?

I do not understand the HW #5 solution for the SEPIC nEET problem where we are told the solution has an error.

I do not understand the first line of the solution. I do see that the secondary voltage, referred to the primary is -vtest(D'/D) .


Also, for the s^3 pole term, I got a value R/(1+D/D')^2. I have attached that, I do not see any error in that, which does not agree with the HW solution.



thanks

    for the attached picture, the solution for the pole is just the part in the upper portion.

    Your b3 solution (term with s^3 in the denominator) is just fine, and it does agree with the solution. Note that D' + D = 1.
