Hi,

Hello,
I found a reference design for 3 phase PFC using a Vienna Rectifier. It uses the C2000 MCU and the design can be found at the following link.

If you have any questions regarding how to do a 3 phase design using the C2000 please repost in the e2e with C2000 in the title so the appropriate applications engineer can answer your questions.

Hi Mike O',
Thanks for your reply. I am looking for 300W PFC ICs like UCC28060 etc.,
Because here, Output power will be 300W only as well as size wise, project cost wise also constraints are there.
I thought that C2000 based PFC controllers are very high end for this application.
Please let me know your suggestions.
Hello,
The UCC28060 is interleaved PFC and will work on single or dual phase input with a single rectifier. As far as 3 phase TI does not offer at 3 phase controller.
However the C2000 can achieve 3 phase input PFC with a Vienna rectifier.
You can do 3 phase PFC with analog controllers. This is generally done with 3 PFC boost pre-regulators one used for each phase. This will require a bridge rectifier for each phase, each PFC stage will need to be galvanically isolated from each other and will need separate isolated DC to DC conversion; as well as, load sharing. In the end you will find that the C2000 is much cheaper.
3 phase line power is generally used for high power applications 300 W sounds kind of low. What is this PFC front end trying to control?

Hi Mike O,
Thanks for your reply.
As per our customer requirement, Input available will be 3 Phase 3 wire only.
We have to design one AC-DC converter , which will give output 24V, 10A and it should pass CE-101 of MIL-STD-461F
Hello,
Thankyou for the information. Your customer can achieve this with a C2000 device using a Vienna Rectifier or correcting each phase with a PFC controller isolation and load sharing as described above. With all the extra circuitry that that is required by individually controlling the phases the cheapest option might be to use the C2000 in a Vienna Rectifier PFC application.
