To illustrate the style, here is a classic problem (similar to UV Exam, July 2020):

Enunciado: Un convertidor Buck funciona con $V_in=30V$, $V_o=15V$, $f_s=150kHz$, $P_o=30W$. Calcule:

Solución esperada (según método Barrado):

1. D = $V_o/V_in = 15/30 = 0.5$ (CCM ideal). To illustrate the style, here is a classic

2. $I_o = P_o/V_o = 30/15 = 2A$.
$I_L,avg = I_o = 2A$.
$\Delta i_L = 0.3 \times 2A = 0.6A$.
Fórmula: $\Delta i_L = \fracV_o (1-D)f_s L \Rightarrow L = \fracV_o (1-D)f_s \Delta i_L = \frac15 \times 0.5150\times10^3 \times 0.6 = 83.3\mu H$.

3. $\Delta V_o = \frac\Delta i_L8 f_s C \Rightarrow C = \frac\Delta i_L8 f_s \Delta V_o = \frac0.68 \times 150 \times 10^3 \times 20\times 10^-3 = 25\mu F$.

Nota del profesor (Barrado): "Verificar que el convertidor opera en MCC: $L > L_crit = \frac(1-D)R2f_s = \frac0.5 \cdot 7.52\cdot150k = 12.5\mu H$. Se cumple." Solución esperada (según método Barrado): 1

Andrés Barrado is a renowned professor and researcher in the Department of Electronic Engineering at the Escuela Técnica Superior de Ingeniería (ETSE) at the University of Valencia. His expertise lies in power supply systems, DC-DC converters, and renewable energy integration.

Over decades of teaching, Professor Barrado identified a recurring challenge: students understood the theoretical operation of a boost converter or a PWM controller but froze when faced with numerical problems involving duty cycles, inductors, capacitors, and efficiency calculations. His response was to create a living document—a collection of problemas de electrónica de potencia that has been refined through countless exam cycles.

While the exact PDF is a specific educational resource, a typical compilation under this title would encompass several key areas, each revealing a specific pedagogical focus: To illustrate the style

If you have obtained (or are about to obtain) a PDF of Problemas de Electrónica de Potencia by Andrés Barrado from the University of Valencia, here is how to maximize its value:

| Do This | Avoid This | |-------------|----------------| | Attempt each problem without looking at the solution first. | Copy the solution without understanding the state equations. | | Recreate the waveforms on paper before checking the PDF. | Skip the "assumptions" section – that’s where the trap lies. | | Compare your final duty cycle calculation with Barrado’s, including parasitics. | Use ideal equations for problems marked "real components." | | Redo the problem after a week – spaced repetition builds mastery. | Treat the PDF as a formula sheet. |
