Hi Ulrich,
Ulrich Goerke said: The PFC converter will operate stably at all loads, down to 0W.
I believe that the power factor decreases because the current waveform is unstable during light loads, but what does it mean to say that the power factor decreases…
Hello Francis,
Thank you for your interest in the UCC2810 PFC controller.
This is an issue that appears to be happening more often these days (or rather, I have been addressing it more often lately.) These previous E2E responses should cover your questions…
Part Number: UCC28180 Other Parts Discussed in Thread: UCC28070 We are using UCC28180 for PFC debugging, and the following problems are encountered:
The output power of the target is 6000W. When reaching 4000W, the PFC current waveform becomes worse and…
