Schematic diagram of buck convereter:

            

Observations and calculations:

                                   

                                  

                                  

Simulink model:-

                   

Procedure:-

      1.design the converter model as above in the MATLAB simulink.

      2.set and apply all parameter value.

      3.give step time and stop time and get result

step:

               

RLC branch:

               

               

               

RESULTS:-

            

Output voltage:-

             

here the output voltage is 30.
