Hi I am trying to generate switching pulses for three level neutral point clamped inverter using space vector modulation technique.
The space vector diagram for a three level NPC includes 6 sectors (60 degree each) and each sector is divided into four triangles.
I wish to know how the triangle where the tip of the voltage vector is present can be identified once the sector is obtained.
Is there any generalized formula that could be used to calculate the triangle number in a particular sector?
Dear Maulik, go through the attached paper, may be you will get the answer for your query..

Maulik
go to pages from 57 to 60 you'll find the answer. If download fails try on Google "Celanovic"

Refer to the simplified algorithm to sample the reference vector in the below attachment.
The PhD dissertation of Professor Josep Pou, has a very interesting methodology in Chapter 3. This solution is well accepted when was used in a closed loop control of multilevel converters.
You can find in google: "chapter 3 josep pou"
His PhD dissertation is in Electrical Engineering, Technical University of Catalonia, Catalonia, Spain, 2002.
