PMP40988: unable to see lab4 java script file to open the scripting console

Hi Filip,

The lab 4 uses the same javascript file as lab 3 as per the firmware user guide.

Best regards, Pawan

Hi Filip,

Software user guide for running all the labs including Lab 4 is located inside C2000Ware_DigitalPower_SDK_5_04_00_00 directory.

C:\ti\c2000\C2000Ware_DigitalPower_SDK_5_04_00_00\solutions\pmp40988\docs

Let me know if that helps or any issues.

Hi Team,

When calculating current reference from outer PI, what is this parameter  TTPLPFC_vRmsAvg_pu? How is it getting calculated and what is the multiplication factor(0.000528) here?

FM,

If you do ctrl+left click the function

"TTPLPFC_EMAVG_MACRO(TTPLPFC_sine_mains.vRms, TTPLPFC_vRmsAvg_pu, (float32_t)0.000528)"

It will show you the moving average function definition in which there is multiplication factor(0.000528). 

#define TTPLPFC_EMAVG_MACRO(in, out, multiplier) out = \((in - out) * multiplier) + out;

This can be seen as a special case for a Low Pass Filter, where pass band gain is equal to Multiplier. You can refer the diagram shown in "C:\ti\controlSUITE\libs\app_libs\solar\v1.2/SolarLib.pdf"

I am attaching related e2e post as well: https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/917276/ccs-tidm-1000-three-phase-vienna
