TMS320F28377D-EP: Switching the sampling method of TIDM-HV-1PH-DCAC routine

Hi Team,

The TIDM-HV-1PH-DCAC routine uses SDFM-based sampling. The customer needs to use the ADC sampling method, he would like to know how to change it?

In the Build-Level1-Open Loop mode, he tried to make some changes, but check that the value of the sampling result register is 0:

1. Shield main.syscfg and migrate the gridconnectedinvlclfltr_settings.h file generated by sysconfig to the project directory;

2. Switch SENSING_OPTION in the gridconnectedinvlclfltr_settings.h file to 2 for switching to ADC sampling;

Thanks，

Annie

Hi,

It seems like the customer is running in grid tied mode.

Please check the thread below.

Best,

John

Hi John,

if you are doing something custom you can always import the project without powerSUITE and change according to you board and design.

Customer wants to know how to operate this?

Thanks,

Annie

Annie,

We do not support ADC sensing on the grid connected code, because the board is using SDFM for the grid output current.

If the customer wants to import the project without powerSUITE they can import directly from here

C:\ti\c2000\C2000Ware_DigitalPower_SDK_3_02_00_00\solutions\tidm_hv_1ph_dcac\f28004x\ccs\gridconnectedinvlclfltr

This will import the project without powerSUITE and the customer is free to modify the project for their development.
