TMDS2MTRPFCKIT questions

1. Do you provide control software for controlling two motors seperately and PFC.

Well, we have this, but we haven't released. We had plans to port to CCSv4 and controlSUITE, but it has slipped in priority due to other motor control development projects.  I can send you the CCSv3.3 version of 2x M 1PFC if you message me.

2. Is it developed in C

Yes

3. I have full version of CCS 4.0, can I work with that or does it have to be CCS 3.3

I haven't tried to import it yet. I imagine there are a handful of issues if you try to use a ccsv3.3. project.  It may be easier to start with the www.ti.com/controlSUITE based 2xM project and then add in the PFC based on the v3.3. project.

4. Can I use seperate JTAG emulator by passing on board emulator in this kit.

Yes.

5. Whats the DC bus voltage in this kit, is it controlled to a fixed value or variable based on the motor speed.

It's variable if you use the PFC stage, this is in the HW Guide.

6. Can you tell me what sort of sensorless is implemented, does it work at very low speed.

It's a sliding mode observer.  It works down to maybe 0.2pu on the pretty low end BLDC motor (and the regulation is not tune exceptionally well at that point). Do you need exceptionally slow speed?  I am working on this.

7. Do you have other code available for two motor and PFC control other than that you supply with this kit (based on TMS320F28035).  Please provide a link

No. The HVMTRPFCKIT has one motor with PFC, latest version has PFC on the CLA.  We are rev'ing the HW on the 2 motor kit, at that time we will re-release a CCSv4 based 2xM 1xPFC SW implementation.

8. Are the inveters MOSFET or IGBT based, can you tell me the rating of inverter and PFC (please also provide the part number for switching device)

FET. DRV8402

When we rev this kit we will use DRV8312 or DRV8332
