Hello all,
we are working on 3KW_2LLC_C7_20 . Dual half bridge LLC convertor
product details link
https://www.infineon.com/cms/en/product/evaluation-boards/eval_3kw_2llc_c7_20/
the Default output voltage is 54V . we can set this output voltage to 50V using GUI
our interest is that we would like to implement with Source code
we have the source code when the product is purchased
Please suggest us setting and lines to added in the source code this would help us....
regards
Karthik

Hi Karthik,
You can actually slightly change the nominal output voltage without changing the source code (which is preferable not to touch) but by simply re-adjusting the resistive partition shown in the attached schematics. Based on the implemented resistors, this voltage partition provides 3.3V in the U_OUT_ADC node when Vout=66,87V. Therefore at 54.3V (nominal Vout) the node voltage is 2.68V. By simply re-adjusting e.g. the value of R235, you can fix the Vout nominal to 50V.

Hi Karthik,
Can you please modify the U_OUT_SET_DEF macro in the source code(LLC3kW_config.h)?
I do not have a kit to try it out at my end. Please try this and let me know the outcome.

hello @Pranava_YN
I have tried to set the U_OUT_SET_DEF 5000 U_OUT_SET_MAX 5400 U_OUT_SET_MIN 4000
but no change found the output voltage was 54V
