This Simulink model implements a closed-loop PWM DC-DC converter.
  • Power stage: switch, diode, inductor, output capacitor, and resistive load.
  • Control loop: output voltage sensing, error with reference (24 V), discrete PI controller, duty limiter, and PWM generator.
  • Simulation uses discrete step (1e-6 s).
  • Scopes and displays included for output voltage and current monitoring.
  • Useful for studying voltage regulation, duty-cycle control, and transient response of a converter under PI control.
