TIDM-HV-1PH-DCAC: Compensation Designer / DC Gain

Robin Houston

Part Number: TIDM-HV-1PH-DCAC
Other Parts Discussed in Thread: POWERSUITE

Hi There,

I'm stepping through TIDUAY6D (Revised May 2019), specifically step 3.1.2.3.3 Step 6: observing invliInst as I raise the DC bus and I do not see it regulating as the bus voltage goes above 50VDC.

As per the note following step 8, i did complete Build 1 steps and verify the voltage and current sensing parameters were correct; I then went back to the compensation designer section to try and review the gain at DC settings but I was not able to follow how this is done.

Can you please advise me on how to alter the compensation designer such that I can complete Build 2 of the user guide?

Note: I had an issue with selecting "COMPI" in the Control Loop Design section initially, however after pasting in an empty ".cookie" file into the folder and restarting CCS I was then able to select COMPI.

Thanks in advance

Robin

I'm trying to (unsuccessfully) paste in a screen shot that shows:

invliRef = 0.02

invliRefinst = 0.02

invlilInst = 0.003

guiVbus = 126.7

I also failed to paste in a screen shot that shows in Compensation Designer:

Comp Number set to "1" and

Style set to "Parallel PI" and has no other choices (TIDUAY6D has DCL_PI_C3/C4 displayed for Style)

Thanks

thankyou

i found in another E2E thread a pointer to control theory seminar and am reviewing that now

I rechecked some of the pre-requisites for Build 2 and have realised that the current and voltages aren't accurately being read , as opposed to what I stated above.

My assumption is that since these values are not correct that this is preventing the Build checks to complete successfully.

I have created a seperate thread for the ADC readings;

Robin, thanks for the update. I will close this thread. Lets work on your fundamental issue on the other thread.
