DRV8301-69M-KIT: The way to realize the cumulative sum of the hardware bus voltage

Part Number: DRV8301-69M-KIT

Dear team:

My customer asked:

The above picture is the part of the development board's schematic diagram that collects the bus current. The network at the input end is the input of the ABC phase current corresponding to the three sampling resistors (the signal end of the sampling resistor under each bridge arm).

May I ask how to realize the total current of the DC terminal of the acquisition bus?

Chinese original:

这个instaspin采集总线电流的原理图,市一个加法器,输入端的网络分别是三采样电阻对应的ABC相电流的输入(每个桥臂下的采样电阻的信号端)通过这个输入道dsp中区采集总电流为母线电流,请问这个采集母线直流端的总电流实现方法?

上面的图片是TI开发板的原理图中的采样部分

Best regards,
