Complete Simulink model of Buck (Step down DC-DC) converter with feedback controller.The controller compares theoutput voltage with a reference value, the difference is amplified and then integrated with a resettable integrator whichis reset with a clock pulse having frequency 10KHz (Switching frequency, you can change the switching frequency).Each clock pulse reset the integrator to zero and in this way a saw tooth wave of frequency 10KHz (same as thefrequency of the clock pulse) is generated which is again compared with the reference value of voltage to get a PWMsignal.The model is accurately designed to give output voltage very close to the reference value ofthevoltage.Visit the link given below to watch full tutorial/demonstration.
