Hi,

 

I would like to know how can I properly determine the inductor value required for running PFC  with IMC102T-F64 controller chip.

Everytime I use inductor value of less than 2.2mH it always triggers PFC gatekill especially when I load (around 150W) but works fine with higher inductor value like 5mH.

My application specs are as follows:

Ac supply: 100 - 240VAC

Input power: 250Wrms(Max) ,20Wrms(Min)

Loading type: Dynamic

Pfc boosted voltage: 340VDC

PFC freq: 40Khz
