UCC25600: CLL resonant converter with synchronous rectification

Hello,

I am reviewing your inquiry and will get back to you shortly.

Regards,

Thank you Mike - waiting on you.

Hello,

I am going to forwarded this thread to the PMP9750 designer to answer your question.

Regards,

Thank you Sheng-Yang.

By the way, the UCC25600 is the greatest resonant controller Texas Instruments ever made.

I have had great success with it, it is simple to use and no other manufacturer has such a simple and effective 8-pin resonant controller.

Regards,

Stephen.

Sheng-Yang, 

If not available for a CLL, have you done synchronous rectification/control for a CLLLC? I am referring to your text: High-frequency resonant converter design considerations, Part 2 which was published in EDN where you speak of using a Rogowski coil to control the SR switches.

Regards,

Stephen.

Thank you Sheng-yang!

Unfortunately the links you sent does not open anything to do with this. Can you please check the links for me? Even if I search for slup399 and slup393 I do not get anything on a resonant converter.

Can you go to www.ti.com and log in with your myTI account and try the link again?

I have done this now three times: both links just take me to the TI home page.

(I have logged out and logged in three times now)

Not sure what's going on there. But what I am referring to is a Power supply design seminar topic: Designing a High-Power Bidirectional AC/DC Power Supply Using SiC FETs. You could do google search, you should be able to find presentation slides and paper of that topic.

Sheng-yang, thank you. Something is wrong. I can see this topic on google, but as soon as I want to download it from Texas Instruments' web site, something goes wrong. I will try tomorrow morning from my work computer. Please do not close this topic yet until I have given you word that I can get to your paper.

By the way, thank you for your great work and for sharing it and for replying to me!

Yes, I can open these links after I log in with myTI account. Maybe you can try to create another myTI account to try again?

Sheng-yang, is there a complete reference design for slup393/slup399?

Sheng-yang, is there a complete reference design for slup393/slup399?

Thank you very much Sheng-yang.

Regarding your paper: A new compact and high efficiency resonant converter:

Would you mind sharing with me how you derived equation 3?

I do not get the same result when I derive it.

I saved the equation derivation process in a software called Scientific Notebook. But I no longer has that software...You can create a linear circuit in simulation software to verify the correctness of the equation.
