PFC tuning: determining skipping area threshold

Step 5: final verification
Once all steps have been performed, the GUI simply checks the supply behavior.
To perform the final verification, the GUI:
•
enables PFC mode change (both PFC frequency and estimated power-based) as the normal mode
•
disables skipping area mode (focus is on mode changes)
•
sweeps the DC load across all the operating modes and checks if it is between the limits
