UCC28951-Q1: Peak Current Mode Control

Hello,

The following will bring you to an application note discussing how to design a FSFB converter that is quite detailed.

Hi Mike,

Thank you for sharing the link. I am looking for materials that talks about how the control and how the gate signals are generated. Do you have a document like that?

Thanks,

Hello,

I found this application note on TI's website that you may find helpful.

Thanks, Mike! I have seen this one, but it doesn't specify peak current mode. 

i saw this following one showed some gate waveforms in PCM, but this app note is for MCU implementation. I couldn't find info on how this works with UCC28951. 

Phase-Shifted Full Bridge DC/DC Power Converter Design Guide (ti.com)

What I am looking for is a detailed description of how to use PCM with UCC28951 and gate waveform of UCC28951 in PCM. 

Thank you very much!

Hello,

The following link will bring you to an application note that shows how to use the UCC289501 is PSFB.  It also has gate driver waveforms coming off a gate drive transformer.

I did look at this one when you sent it the first time. The only gate waveform in the app note is Figure 4-1, but it does not show gate signal of Q1~Q4. 

Thank you anyway, i will take a closer look .
