CCS/TIDM-1000: In the official TIDM code, the frequency and amplitude of the input voltage change. Does the code need to be modified?

Part Number: TIDM-1000
Other Parts Discussed in Thread: POWERSUITE

Tool/software: Code Composer Studio

thank you for your help，There is no parameter option for voltage amplitude and voltage frequency in the GUI. How do I choose the input voltage to be 208V/60HZ or 400V/50HZ?

In the pfc3phvienna_settings.h file, ""#define AC_FREQ 60" AC_FREQ is the frequency of the AC input? If so, can it be changed to 400HZ?

Looking forward to your reply, thank you!

Hi user3636465,

The code does not need to be modified for 208V/60HZ or 400V/50HZ. That is why you only see the AC_FREQ in the settings.h.

Thank you！What is the meaning of AC_FREQ in the settings.h. file?What is the role in the program?If the input frequency is increased to 200HZ, is this parameter to be changed to 200?

Hi,

This parameter is not used in the reference design and we will update the software in the next release. You can ignore it and you don't need to change anything in the code. However, for this reference design, we only tested the 50Hz and 60Hz conditions. The tests under other conditions which are not covered in the user guide should be done very carefully by the users.

Regards,

Chen

thank you for your help！

In the code, there is no limitation on the input voltage and input frequency. At frequencies other than 50-60HZ, at least the code can work regardless of the output effect. Can I understand this?

Ren

Yes, your understanding is correct. But as I mentioned before, the tests other than 50/60HZ are beyond the coverage of our reference design. Hope that helps.

Thank you for your reply. Can all core algorithm users see the source code? Or packaged, can only be used? Is there an documentation for the algorithm?

Hi Ren,

All the control algorithm related code can be seen in the released digital power sdk. The code and the user guide can be found in the page below:

Hi Chen,

"The <solution>_settings.h file cannot be modified manually; the Kit.xml and solution.js files are used internally by powerSUITE and cannot be modified by the user. Any changes made to these files will cause the project to not function properly."So I am worried that this will limit my development.

Hi,

So basically in the <solution>_settings.h file, we have user code section and non-user code section(the powerSUITE code section). The boundry is /* USER CODE START (section: User_Section) */

For the code in the user code section, you can directly modify them in the <solution>_settings.h file and click save. For the code in the non-user code section you have to change the parameters or settings through main.cfg GUI. You don't need to worry too much about the the Kit.xml and solution.js files.

Above is just a general answer to your question. If this does not solve your issue, can you please tell us more about "The <solution>_settings.h file cannot be modified manually" in your question.

Thanks.
