I have to simulate a buck dc to dc converter in my project. I think the circtui is correct, but the DC output I am getting is exactly equal to the DC input, except that there is some ripple. That too very less. The frequency I have given is 100 khz. Duty ratio of pulse generator is 1/3. What am I missing. Why is the output equal to input?

Here is the link to the circuit in simulink:
