3 phase in PFC (UCC28019A, UCC28180, UC3854)

Pao,
I'll contact the appropriate product group here. What power level do you need here? What's the application?
Regards
John

Dear John,
Input voltage : 90~264Vac,
Output voltage 380~390Vdc
Power : 1~1.2KW(Now), ...3KW, 5KW(2017 project)
PF : 0.95.
Application : 3 phase AC PFC, industry Fan.

Thank you for your great support.

Hi Pao,

I am responsible for high power controller solutions covering PFC and isolated DC-DC and I do not have an example for your 3 phase AC PFC configuration to a single PFC output feeding a DC-DC stage. I think you may have to consider a single PFC + Isolated stage to work with one phase at a time and combine the three input AC phases after the isolation stage but my group does not work with 3-phase power in these applications. I am checking to see if another group can help.

Hi Brian,
Thank you, Do you have refence schematic and reference code could share to us ??
We will learn first.

Thank you for your great support.

Hi Pao,

Could you post your schematic and reference code request to the "C2000 32-bit Microcontrollers Forum" as I do not have a way I can figure out to route your question to that forum. They have the experts to help you.
