Hi,

What is the minimum in put AC frequency with TIDM-1000? According to key system specifications in table 1. of "TIDUCJ0G", it should be 50/60 Hz. I think it is related with PLL in the firmware and I would like to know if I can reduce the input AC frequency to 30Hz or so. How to adjust this parameter on firmware side? Thanks.

Hi Ming-Hung,

The reference design is validated with 50/60 Hz only. Incase, If you really want to change it, you can use the non-powerSUITE version of the code.

Thanks,

Hi Uttam,

May I know where to download the non-powerSUITE version of the code? Thanks.

browse from CCS to this location: ti\c2000\C2000Ware_DigitalPower_SDK_4_04_00_00\solutions\tidm_1000\f28004x

Hi Uttam,

I have imported non-powerSUITE version of the code. May I know where to adjust the PLL for input AC frequency? Is there any document describing non-powerSUITE version of the code? Thanks.

You can change the AC input frequency in vienna_settings.h and some hardware related in vienna_user_settings.h

Unfortunately, there is no non-powersuite based documentation.

C2000ware_DPSDK_guide , oneMCUcodingStandard might be helpful

Thanks & Regards,

Hi Uttam,

There is also a "#define AC_FREQ_HZ ((float32_t)60)" in powerSUITE version of the code (pfc3phvienna_F28004x). Acutually, I have compared non-powerSUITE and powerSUITE versions of the cod; however, they are almost the same in those *.c and *.h files. May I know what is difference between them? What are PLL tolerance if I configure the "#define AC_FREQ_HZ ((float32_t)60)" (i.e. +/- 10Hz or so)? By the way, the link oneMCUcodingStandard is not accessible, and please let me know how to download the document. Thanks.

PowerSuite has a GUI interface for simpler understanding whereas, Non-powersuite is more generic to modify as per user requirments.

Hi Chen,

I checked with experts. regarding the power suite and non-power suite query. There is no fundamental difference between the 2 types of projects.

The user guide has some explanation about the code structure. Unfortunately, the link I shared is not accessible outside TI so it shouldnt work for you.

Best Regards,

Uttam
