I hate the term "space vector modulation" https://www.google.com/#q=space+vector+modulation

The way it's described is always overly complex. The signals produced when using it are no longer sine waves and people have even done papers doing spectral analysis on the output. There's matrix math and all sorts of academic blah. But in the end you can do it in 4 lines of code:

s = (min(a,b,c)+max(a,b,c))/2;

A = a-s;

B = b-s;

C = c-s;

In EE terms, we add a common mode signal to all 3 in order to avoid hitting voltage limits for as long as possible. The load can't see it.

Anyway, the amount of analysis and math around this concept always seemed like a whole lot of intellectual self gratification, so I prefer to substitute a different M word for modulation.
