Buck Converter — Simulink Walkthrough
A minimal buck converter Simulink model, open-loop.
How a Buck Converter Works
A PDF that walks through the buck converter from first principles — topology, duty cycle, and the waveforms you should expect to see on the bench.
A video walkthrough is available on YouTube.
What is in this PDF
- Buck converter topology: switch, diode, inductor, capacitor, load.
- Duty-cycle derivation in continuous conduction mode.
- Inductor current and output voltage waveforms in continuous and discontinuous conduction.
- Inductor sizing from a ripple specification.
- Capacitor sizing from a ripple specification.
- The first-order mistake every student makes, and why it is wrong.
