HW5.3 Incorporating load resistance into model

Hi,

For HW5.3, I built the Simulink model of the boost converter using the structure as our first model of the buck converter. I compared the resulting ||ZD|| with the closed form solution on page 382 of the textbook, and they don't match. The textbook solution has the load resistor R in the solution. My model doesn't have this resistor because we model Iload directly.

Should my model include R directly or is it equivalent to model it using Iload=V/R?

Thanks.

    Solving for Zd and Zn uses AC analysis. Any AC analysis is predicated around the assumption that the DC operating point is correct. Without a good DC op, AC output can look close to expected, or look like total trash depending on how far off the DC op is.

    Have you checked your DC op to make sure it makes sense?
