2. Use the average current of diode in a Boost converter operating in DCM mode to model the converter in a large signal mode. Linearize the model and find the equations for \begin{equation*} H_1(s) = \frac{\tilde{v}_o(s)}{\tilde{d}(s)} \text{ and } H_2(s) = \frac{\tilde{v}_o(s)}{\tilde{v}_{in}(s)}. \end{equation*}

Step 1
In DCM (Discontinuous Conduction Mode), the current through the inductor in the Boost converter goes to zero during a portion of the switching cycle. This means that the diode conducts only during a portion of the cycle. The average current of the diode can be Show more…
