Hi,
I've build a 1800 Watt PFC by using TI 's reference design, TI excel sheet etc. The PFC is doing great till 1800 Watt and above till 2500 Watt. I would like to decrease the power limit till 1800 Watt such, that in case the power exceeds the PFC voltage will decrease. However I tried to decrease the PKLMT voltage from 3.7 till 3V but my PFC will not limit its power at 1800 W. The output voltage from my current transformer is peakto peak 2.5V at 1800W, which I quess is too low.. It should be in de order of 3V. Anybody some idea or tips ?
