This write-up summarizes the key concepts, typical problem types, and resolution strategies found in Power Electronics course materials for a 6th-semester curriculum. The problems generally focus on the analysis, design, and simulation of power converters. Calculate the duty cycle and current ripple

Example: "A Buck converter has $V_in=20V$, $V_out=5V$, $L=100\mu H$, $f_s=100kHz$. Calculate the duty cycle and current ripple." Determine: a) Average output voltage, b) RMS current,

Typical Problem: "A single-phase full-wave controlled rectifier feeds an R-L load. The source is 220Vrms at 50Hz. The firing angle (α) is 60°. Determine: a) Average output voltage, b) RMS current, c) Power factor, d) Distortion factor." SEPIC in CCM/DCM

Barrado’s Twist: Instead of a pure R-L load, the problem adds a back EMF (counter-electromotive force) simulating a DC motor. You must calculate if the rectifier is in continuous or discontinuous conduction.

This is where Barrado separates the A students from the C students.
