GUI normal mode
7.1
Power metering
During normal mode,
sends the information used to compute the actual power delivered by the PFC,
that is:
•
the estimated power computed by the power integration algorithm
•
some factors used for power estimation correction :
–
Vin (mains) voltage
–
PFC mode of operations (DCM, Valley Skipping, TM)
–
Time between PFC pulses (DCM mode only)
–
Phase angle modulation ratio (at low power only)
•
Some flags about temporary PFC faults (Deep DCM, PFC_OCP1, etc.)

GUI metering information panel
Note:
If STNRG011 power messages are disabled, the boxes shown above are empty.
Important:
Power metering is not available in Burst mode (to save MCU power energy, hence efficiency at low power).
7.2
PowerGraph report
By checking the box
Display PowerGraph
, the history of PowerGraph event is displayed, to see the long-term
stability of the power supply or mode changes versus load.
