step 01
connect the bolcks as shown below
step 02
set the input voltage v1=48 volt
and pulse generator as shown below
step 03 run the model by keeping load r=8 ohm and you will see the plot as shown below
now duty ratio in pulse generator is kept 58.33 percent for given switching frequency which gives us the required result overaing arround 28 volt with less ripple and input voltage 48 vlt.
Please show design and simulation esign a buck cnvarr such ha2 the oupu vol?age is o8...
