Hello experts!
my GP is to design an offline DC/DC converter ( LLC ) for cordless home applainces similar to the attached file, now I am aware of how to design LLC for conventional Chargers (wired) to some extent, but i get compeletly confused when it goes to design LLC converter for wireless application specially how to integrate the coupling factor in the LLC design, I have Knew that LLC isn't the optimal resonance tank to use with WPT due to the coupling factor, but we have choosed it because that our coupling factor values expected to be high > 0.7 in home Applainces applications because the distance btw the coupled coils is small, and certainly for the high efficieny LLC provides
I hope u suggest any AN or Refernces help my in the designing the LLC tank, certainly, I Would happy to hear any general recommendation about the project as well.
Thank u for yout time and considrations
