Hi
I am studying a dc dc converter model. My friend drew this circuit and got this graphic.
I added his circuit and graph . But I draw same model , same numbers for resistors capacitors v pulse source ,inductor, diode but my graph is very different.
Actually my V pulse source looks like doesn't working . I added my Pspice design and graph . What is my mistake ?
Could you please help me ?

Welcome to AAC!
I simulated the post #1 circuit in LTspice and got a similar waveform to that in Fig 6.6.
I could replicate your waveform by omitting R1. Are you sure your circuit exactly matched that in Fig 6.6?

In my friends graph there is no dot . Its already connected . I changed diode it works now but again graph different

That makes no sense. It is inconsistent with other connections in the diagram.
There should be a connection dot indicating connected wires.

The base connection dots should look like this:
