For buck converter, at the start of Toff, the inductor current will flow through the shottky doide or the NMOS transistor, there will occur oscillation at the front end of the inductor.
my question is why there is an oscillation and what parameters determine the characteristics of this oscillation?

Re: dc/dc converter

Hello

What is the frequency of those oscilations?
What is the walue of your inductor?
Did you model parasitic resistance and how big it si?

It won't be bad if you attach some pictures of schematic and waveform.

Best regards.
