UCC2897A: Peak Current Mode

Andres Gomez
Intellectual 450 points
Part Number: UCC2897A


Tool/software:

Hi.

I have designed before Peak Current Mode for non-isolated dc-dc converter; however, I have a difficulty to understand the behavior of the model using isolated dc-dc converter. I was reading this document: "UCC2897A Peak Current Mode Active Clamp Forward Converter Small Signal Modeling" and I saw this transfer function control-to-output voltage. Is this only work for UCC2897A or can it be used to other controllers that using ACFC topology?

I also found this paper and presentation from Texas Instruments that talks about Peak Current Mode Control Applied for the Active Clamp Forward Converter

If you could please guide me a little bit about this.
