TIDA-010062: guidance for PFC lab2, how to choose Gi value

Hi Team,

for PFC Lab2, we change Gi for several values and finds it's hard to choose a right value which can make the loop stable at all the input voltage/output current conditions.

 we use SFRA and Compensator Designer for Gi adjustment, when Compensator Designer shows system is stable at a specific Gi but practical test shows it's not stable.

do we have a more detailed guidance on how to understand the loop tuning and how to set values?

thanks.
