Part Number: PMP4259
Hi TI expert,
I'm working on my PFC boost converter prototype based on PMP4259. I have reached to the point that I can supply up to 50% of maximum load (3KW) but PF is lower than my expectations. Below I share voltage (yellow) and current (pink) of the boost inductor for one phase and I assume in some portions it has weird waveform which most probably is responsible for low PF (87% @ 20% of L_max). Can you comment on these waveforms?
Thank you for your time.
