Part Number: UCC3817 Hello guys,
One of my customers is evaluating UCC3817 using TI official EVM.
They calcurated Rsense(R14 in Figure 9 on page 16 of the device datasheet) value with the design procedure document in the following URL
and they for the calculated…
Part Number: UCC3817 Other Parts Discussed in Thread: UC2854 , , UCC28180 My question or observation concerns the PFC part differences between the ucc3817 vs. UC2854 units
The internal multiplier output (Imo) is hard-connected either to the inverting or non…
Hello,
I looked at the waveforms and there are flats spots in the sine wave near cross over. Even these waveforms would pass EN61000-3-2 harmonic content.
I have to be honest that all of my PFC designs have been to meet EN61000-3-2 and were designed…
Part Number: UCC28513 Other Parts Discussed in Thread: UCC3817 , UCC2817 This is a follow-up to the case no. above.
We were able to mitigate the current distortion. But, now the PFC output voltage seems unstable under certain conditions.
The attached report…
Part Number: UCC3817A Other Parts Discussed in Thread: UCC3817 , UCC28064 , UCC28180 Hi
I would like to ask if this IC UCC3817 is capable of operating at 400Hz line frequency without any trouble and meeting DO-16 harmonics standard.
Do you have any application…
TO ANSWER YOUR QUESTION I AM FULL WAVE RECTIFYING 3 PHASE POWER INTO A SINGLE DC BUS. WHAT I NEED TO KNOW IS HOW THE COMPENSATION AROUND THE UCC 3817 IS AFFECTED.. THANKS.
Hi Jared,
Thank you for the query.
The UCC3817 and UCC3818 are second generation possible p2p replacement for the UC3854.
You can also consider the UC2854x family.
All of the parts mentioned are compatible from a pinout, package & functionality perspective…
