UCC28180: Input current

Part Number: UCC28180

Hello!

I'm using ucc28180 in new design. Now it works well but, I noticed that there are a lot of spike or inrush current in main ac at 230V during strong transient in proximity of peak of sine current (looking pic A) . Is this normal? There's a way to eliminate it?

However pfc works well when average current is low (looking pic B at left and right side).

Thanks and regards

Cristian
