3.5 푸 V D, C RV - Fig. 3.32 Nonideal buck converter, Problem 3.5. In the buck converter of Fig. 3.32, the MOSFET has on-resistance R, and the diode forward voltage drop can be modeled by a constant voltage source V. All other losses can be neglected. (a) (b) (c) Derive a complete equivalent circuit model for this converter. Solve your model to find the output voltage V. Derive an expression for the efficiency. Manipulate your expression into a form similar to Eq. (3.35).
