So I'm really rusty on phasors, I was reading that a space vector current was(adsbygoogle = window.adsbygoogle || []).push({});

i(t) = I(cos(wt)<0 + cos(wt - 120)<120 + cos(wt - 240)<240 ) = 3/2 * I < wt

and I couldn't figure out how that could be so (still can't, please help)

So I tried to go back to basics and I went back and read:

A = CosΘ.Cos(wt) + Cos(Θ - 120).Cos(wt - 120) + Cos(Θ + 120).Cos(wt + 120)

= 3/2 * Cos(Θ - wt)

so I went back to Trig identities.....and pages of scribbling later still couldn't figure it out.

Does anyone have a proof for either of these?

Thanks!
