Hey guys! I would just like to share my success in building a 2KW PFC with the following specs:
PFC IC: UCC28019A from T.I. (got some samples)
Input: 230VAC
Output: 380V, 5.6A (around 2100W)
When I started out, I had trouble with the inductor. I used an ETD-59 with N87 core. At first I tried it ungapped and got HORRIBLE results at 300W (LOL). So I increased the gap until I got it right.
I'm posting waveforms on here. If you have questions, just fire away. If you want a copy of the schematic, just send me a message. Thanks!
For the waveforms:
Yellow: Line Input voltage
Light Blue: Current (either inductor or output, you can figure it out easy enough)
Purple: Output Voltage
