Hi all
I'm working on SVM in my TMS320F2812 and I'm reading the documentation of EV units (SPRU065E). In my opinion there is an error in the rappresentation of space vector, so I'm wasting lot of time trying to understand what are the output.
In paragraph 2.3.1there is a right table of switching pattern, and you say that the rappresentation is on the d-q plane, that is the static 2-axis plane. What do you calculate vectors? The Clarke tansform is
Ud = Ua - 0.5 Ub - 0.5 Uc
Uq = sqrt(3)/2 (Ub - Uc)
If I calculate the vector that you define 001, for you U0 (the vector at 0°) with the values in your table I get:
Ud = (-1/3) - 0.5*(-1/3) - 0.5*(2/3) = -1/2
Uq = sqrt(3)/2 (-1/3 -2/3) = -sqrt(3)/2
that is, exactly, U240.
If you try with the other vector, you see that phase a is mistaken with phase c.
So, what I have to expect in output? The errata notation or the correct one?
