UCC25600: LLC converter design, Attainable peak gain plot

Mar Far

Part Number: UCC25600

Hello, I am reading SLUP263 (LLC converter Design), (figure 12.a page 17), trying to draw the "Attainable peak-Qe" plot in MATLAB, to select proper Ln and Qe.
However, I do not know how to draw the Attainable peak gain plot! Can an expert help?

Hi Mar Far,

Attainable peak gain can be plotted using below formula:

Here k is Lm/Lr ratio

You can implement this function in the matlab.

Hi,

The equation was derived from the equation 15.7 in the following reference:

LLC Resonant Converters: An Overview of Modeling, Control and Design Methods and Challenges | Now Foundations and Trends books | IEEE Xplore
