Original question:

UCC25600: CLL resonant converter with synchronous rectification

UCC25600: CLL-resonant converter of Mr Sheng-Yang Yu

Part Number: UCC25600
Other Parts Discussed in Thread: PMP9750

Tool/software:

Hello Mr Yu,

I am having trouble to download the gerber files of your PMP9750 design.

Can you please help me with this?

Have you tried your CLL resonant converter at a fixed frequency using a full-bridge with phase-shift modulation to regulate the output voltage?

    Hi,

    I can download the gerber files no problem after I logged in to my TI.com account. Please try to log in with your account before you try to download the files.

    No, I have never tried to do fixed frequency & phase-shift modulation control on a CLL converter. But basically doing so will turn it into a phase-shift full bridge converter (if we are using full bridge at the primary side).

    Regards,

    Sheng-Yang Yu

    Hello Sheng-Yang,

    Thank you very much - I will try again.

    I already have a phase-shift full bridge with the CLL parts in it, designed to resonate at the switching frequency and the current in the primary is a sine wave!

    I am attaching a photo to show you.
