Hi,
I want to use UCC28019 to design 1600W PFC power. When the power is 1300W, the current waveform is distorted. Please see the screen (location 1) as attachment.
My questions are:
1. What's the possible reason for the current distortion?
2. How to avoid the current distortion and improve my power to 1600W?
Thanks.
