**Part Number:**UCC28180

Hi

I am designing a 2.5KW PFC with ucc28180.

Vinmin=160

Vinmax= 270

Efficiency expected= 98

Vout= 400V

Based on a 40 percent ripple ( Inductor current) I calculated the boost inductor is 156uH.

I have the following questions

1) Whether it is a DC bias inductance or is it a full load inductance??\

2) I have a bigger inductor which is used in another design of 600uH ( bigger core) can carry 25A . What happens if I use this inductor??

3) basically what happens if I use much bigger inductor than calculated one??
