Part Number: UCC2818 Tool/software: Hi,
I am trying to make sense of the behavior of the UCC2818. I was under the impression that the soft start voltage will control the rate of rise of the bus voltage during start up. However, that does not seems to…
Hi Ramahadullah,
Thank you for finding that paper and providing a link to it. Clearly your system is suffering from the slow-scale period-doubling instability that is investigated in the paper. (Note: Reference [6] in that paper refers to bifurcation…
Part Number: UCC2818-EP Other Parts Discussed in Thread: UC2854B-EP , UC2854 , UCC2818 Tool/software: Hi TI team
I would like to know which among these PFC ICs (UCC2818-EP and UC2854-EP) can have <5%THD on the input current for input frequency of 360Hz…
Part Number: UCC2818-EP Other Parts Discussed in Thread: UCC2818 , UC2854 Tool/software: Hi TI team,
I have following requirements
Input voltage -100Vrms to 134Vrms
Frequency- 360Hz to 800Hz
output voltage- 400V

I am planning to UCC2818…
Balakrishna,
You have two E2E threads open at the same time on the same topic. The only difference is that this thread uses "UCC2818" as the part number in the thread title. I have previously closed this thread.
You have opened it again with a…
Part Number: UCC2818-EP Other Parts Discussed in Thread: UCC28070A Hello,
I will rectify the 3 Phase 400 Hz 115 VAC input supply to DC (270 VDC) with the bridge rectifiers shown in the figure, and then apply boost PFC to 450 VDC with the UCC2818-EP integrated…
Part Number: UCC2818 Hi,
In the following thread, " Adding a circuit to delay when OVP/EN goes high sorted the problem. " is mentioned, but could you tell me exactly what circuit you added?

Hi,
I found the following documentation for designing a PKLIMIT peripheral.
https://www.ti.com/lit/an/slua321/slua321.pdf
Is there any documentation with formulas for determining the constants of each resistor or transistor? Or could…
Part Number: UCC2818 Other Parts Discussed in Thread: TPS62933 Hi,
I checked the internal block diagram of UCC2818.
It looks like the input from SS pin is connected as power for ERROR AMP.
↓UCC2818
Is it correct that the connection diagram between…
