Part Number: UCC28951 Hello,
I have run some simulations of a PSFB with Pspice and I have seen that there is some relashionship between the shim inductance and the maximum duty cycle.
Theoretically I could avoid the shim inductance and only use the leakage…
Hello,
j is the square root of negative 1. When it comes to S(f) this is referred to as angular velocity and is a function of frequency. Gc(f) is the control to output transfer function. The gain will move with frequency.
When it comes to setting up…

Hello,
I read through the thread and the question is in regards to the sync function.
The sync occurs on the trailing edge of the sync pulse. The below snippet from the data sheet show output A and B vs the sync signal.
The waveform below you took…
Part Number: UCC28951 Other Parts Discussed in Thread: UCC2895 Hello
I'm goig to test the UCC28951 on a PSFB already driven by UCC2895.
I want to evaluate the UCC28951 designing an adapter PCB in order to replace the UCC2895.
I have some doubts:

Hi,
We are using the UCC21520-Q1 Isolated Gate driver for the UCC28951 PSFB. Shall we use single isolated DC to DC at the Primary side for both Gates power VDDA &…
Part Number: UCC28951 Other Parts Discussed in Thread: UCC28950EVM-442 , UCC28950 , TINA-TI Hello,
I am working on design of 2.5kW 48V PSFB DC-DC converter using UCC28951 Controller IC. (input voltage: 370 to 410 Vdc)
We tested using on-board UCC28951 IC…
