Linear DC Power Supplies - Designing and Building Custom DC Power Supplies

This course explains how linear power supplies convert AC to regulated DC, including component selection and voltage-regulator circuits. It then demonstrates building and testing a variable 2–20 VDC bench supply rated up to 2.5 amps, with attention to chassis layout, wiring, assembly, and mains safety.
