Can you suggest an automotive analog PFC controller for the following…
Part Number: UCC28050 Other Parts Discussed in Thread: UCC2818 , , UCC3818 Could you tell me more about compliance with current harmonics standards BOEING DO160/F/or G section 16.7.1 and AIRBUS ABD0100.1.8.1/C section 6.2.1.4 (more constraining). In the…
Part Number: UCC2818A-Q1 Other Parts Discussed in Thread: UCC2818
This is a block diagram of a CCM PFC. I want to understand the role of the feedforward constant block here.
This is the functional block diagram of UCC2818A-Q1. Can anyone explain…
Hi Sam,
We don't have a PFC rated for military applications. We have an analog PFC rated for Hi Rel applications, the UCC2818-EP ( https://www.ti.com/product/UCC2818-EP) .
Let me know if you are still considering the UCC28056 for your application…

Hi Experts,
Customer would like to continue this thread for additional request:
(+) UCC28513: The PFC function is lost above 220Vac
Customer reviewed the…
Typically 20%. How typical? Would 13.6%, 10%, 5%, be ok?
So we sync a UCC2800 and UCC2818 and a competitors PWM to 312.5kHz. I have a requirement to freerun at 270kHz ±10%. Hence the 13.6%.
How close can the freerun and sync frequency be before…
Hi Dinesh,
In CCM PFC the gate drive speed is quite important so been able to turn on and off the Mosfet quickly to minimise switching losses.
I suggest adding a totem pole NPN/PNP driver to the design with an option to not fit the transistors and…
Hi Steve,
The UC2854B has an oscilllator similiar to the UCC2818 and it can be synchronised as in this configuration:
This drawing shows the pfc being sync'd to a downstream pwm. In your design you will probably not require C1,D1 and D2 .
The…

I posted this a while back : https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1495822/ucc25660-afpc-not-starting-working-ucc2818…
Hi
The TI analogue PFC controller portfolio does not support three phase applications.
Normally three phase application are higher power level and customers are happy to use more sophisticated controllers like C2000.
An alternative approach for…
