Hello every one ,
I have purchased two 3Kw_2llc_c7_20 Evaluation Boards (DC-DC converter)
when I have Given rated 400VDC , one board is operating in normal mode giving 54V output But another board is not giving the output, I have tried from GUI interface both Boards are working properly I will Share you the screen shot below of GUI window
In Second Board Memory fault status register is highlighted in RED color I have shared the GUI manual in that page 8
Appendix A status register description there is a explanation about memory fault
but if have erased the MCU flash and dumped Hex file given by the Product registration information its not working
please guide me the following issue.
I want board 2 to work as normal mode like Board 1 is working .. I have source code given by Infineon for 3Kw_2llc_c7_20
and also HEX file.
Solved! Go to Solution.

Hi,
I understand that you are looking to implement batter charging spec using the eval board.
But as already mentioned in the following thread, this eval board is not intended for battery charging ( CC and CV mode),
It is recommended to use a eval board that is designed for battery charging.
I suggest you to use EVAL_2KW_48V_CHAR_P7 eval board. This evaluation board is targeted for battery charging applications. The evaluation board uses a dual-boost PFC + half-bridge LLC power supply solution. Infineon’s latest CoolMOS™ P7 Super junction MOSFET enables natural convection cooling. The design has a battery management control system capable of charging both lead-acid and Li-ion based 48V batteries in the different charging modes. The charging profiles correspond to the latest trends of battery charging. Furthermore, the evaluation board offers the possibility to set the nominal battery capacity in order to adjust the charging currents of different battery sizes. In addition to this, it grants a parallel operation of two modules that can extract 4kW maximum charging power. This enables fast charging for Li-ion batteries.

Hi,
Thank you for posting on the Infineon community.
1) From your description I understood that second board is not at all functioning and there is no output obtained from the board. But in the attached GUI, I can see that the working/measured voltage U2 is around 54V.
Can you please reconfirm and let me know?
2) In the GUI please check only LLC1, LLC2 and Automatic SR operation and try running the demo board. Please do not check SR1 and SR2 operations initially.
And one more question, from which channel did you receive the source code?
Regards,
Abhilash P

hello @Abhilash_P thank you for your response
1) From your description I understood that second board is not at all functioning and there is no output obtained from the board. But in the attached GUI, I can see that the working/measured voltage U2 is around 54V.
1) ANS
Board 1 is working fine with GUI and with out GUI
and Board 2 is working only with GUI
2)And one more question, from which channel did you receive the source code?
2)Ans
please open below link it will take you to the product
https://www.infineon.com/cms/en/product/evaluation-boards/eval_3kw_2llc_c7_20/
as it was an DC DC convertor we would like to implement the battery characteristic in that convertor it has CV support we would like to implement CC for that Board
we have source code for that board but need to implement CC mode pls guide us

Hi,
1. Board 1 is working fine with GUI and with out GUI
and Board 2 is working only with GUI
Ans: The board has to work with the GUI interface.
I think 2 threads has already been created with a similar request. Can you please refer to it?

hi @Abhilash_P
Both the request were posted by me only yes they both with similar issues
kindly help us to solve it
we would like to implement CC via soft ware in that control card to get Battery characteristics
regards,
karthik
