Other Parts Discussed in Thread: CONTROLSUITE

1.I am trying to implement 3 level NPC.

a.I have written code for 3 -level svpwm. I want to avoid using any look up table for switching sequence. What are other options then?

b. Also how to implement SPWM using only one carrier waveform for three level NPC. I am taking absolute of sin wave and then comparing it. But I have to give it to four switches.How can we do it ?

Regards

Richa,

Can you tell us about the application you are trying to use this for?

We have several examples of how to run SVGEN etc in controlSUITE..

C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.1

some are very old app notes that you can use to understand the concept

www.ti.com/.../spra524.pdf

in addition to the motor contro library documentation

I want to test three level NPC inverter for standalone and grid connected operation. I have written code for three level SVPWM. But it depends on look up table and many if0else loops.

So, I wanted to know if there is any other method to implement 3-level SVPWM without look-up tables. Control suite has code for 2 level SVPWM only.

Richa,

This is closest we have

Also if it is for solar, then can you tolerate SVPWM? Is there a transformer in the system
