Part Number: UCD3138PFCEVM-026 Hello,
We bought UCD3138PFCEVM and I am trying to test it.
I followed the steps mentioned in the user manuals and connected the PFC Eval to 240Vac input
On the first attempt, I think only the bridge rectifier was operating…

Using the C2000 series controller TMS320F2833528335 for programming and then experimenting, the main circuit hardware is designed by itself, just referring to the circuit of UCD3138PFCEVM-026.
Part Number: UCD3138PFCEVM-026 Hello, experts
I found that you have selected 40% for the L ripple parameter of the boost inductor on the UCD3138PFCEVM-026 evaluation board. In the current continuous mode, the 40% inductor current ripple is very large…
Part Number: UCD3138PFCEVM-026 Other Parts Discussed in Thread: UCC28180 Hello, experts
in the UCD3138PFCEVM-026 evaluation board, why is the boost inductor parameter 327uH? According to the design parameters of the evaluation board, the calculated boost…
Part Number: UCD3138PFCEVM-026 Expert, during single phase operation, I switched from 50V to 110V, the circuit worked normally for a while, then suddenly stopped working. I checked the single-phase connection, but I still can't find the problem. May I…
