While the PDF is theoretical, Barrado encourages using simulation software (like PSIM or LTSpice) to verify your handwritten results. Many PDF editions include a final section comparing hand calculations to simulation waveforms.
Below are the essential equations frequently used in Andrés Barrado’s problem sets:
Buck Converter (CCM): $$V_out = D \cdot V_in$$ $$\Delta I_L = \fracV_out(1-D)L \cdot f_s$$ $$\Delta V_out \approx \frac\Delta I_L8 \cdot C \cdot f_s$$ While the PDF is theoretical, Barrado encourages using
Boost Converter (CCM): $$V_out = \fracV_in1-D$$
Rectifiers (Controlled): $$V_dc = \frac2V_m\pi \cos(\alpha)$$ (for single-phase full-wave) Below are the essential equations frequently used in

Statement:
Simulate a 100W synchronous Buck converter (Vin=48V, Vout=12V). "Problemas de 6to de Electrónica de Potencia –
Expected conclusion (from Barrado’s teaching materials):
Efficiency peaks between 100-200kHz for MOSFETs with moderate Qg. Above that, switching losses dominate; below that, inductor size and conduction losses rise.
