Hi
I am using L4985A for my 110W PFC design. During testing boost inductor current is getting distorted when i increase the load. And also, audible noise from the boost inductor. Here I attached the waveform. I used eDesign suite for designing and simulating the design. I am attaching my circuit herewith. Please give your suggestion to solve this issue. Below given the eDesignsuite design page.
Thanks
