Hi,
Just got a PFC stage in.
The peak current is limited to just 3% above the maximum peak current thats seen at max load, minimum vin.
Do you agree this is too tight?
For PFC, peak current limitation should be to at least approx 10% above atual max peak current?
This is because PFCs have slow feedback loop, and if the sense current limit is too tight, then the PFC will just oscillate, "motor-boating" from
max to minimum output...would you agree?
