The role of inductance in Boost circuit.

Hardware design

As shown in the figure, this is different from the Boost topology I usually see. There is an additional inductor L2. What is the use of this inductor?

What is the sensitivity of L1 and L2, and what specifications is L2 made?

The main purpose is to reduce the ripple. If the output has ripple requirements, it is best not to lose it.

Reduce the switching ripple noise of the PFC circuit? Conducted differential mode inductance?

I have added a common mode inductance to this place, but I haven't tested the effect of adding or not adding to conduction.
