Why does SimScape inductor exhibit not symmetrical current behavior?

Hello,

I am modelling a PWM switching whose model is shown here below, where the Pulse generator represents my previous PWM stage.

So far, I am experiencing some weird behaviour in the inductor, I see how it does not exhibits a symmetrical behaviour in its current, as in show below when showing the input to the MOSFET and the output after the filter

Making using of SimScape tool to check signals led me to the inductor

Focusing in the inductor current ,I_L, I have show that delay in red

I wonder why does this happen, is it owed to how it was modelled? Any ideas?

Thanks in advance,

Regards!

This seems to be wierd I use the following model

I see that the voltage accross the inductor is not the same

Simscape output in both terminals of the inductor

if I overlay the positive and negative terminals of the inductor
