Line 131: Note that looking down the columns for the active switching vectors V<sub>1-6</sub>, the output voltages vary as a pulsed sinusoid, with each leg offset by 120 degrees of [[Phasor (electronics)\|phase angle]]. To implement space vector modulation, a reference signal V<sub>ref</sub> is sampled with a frequency f<sub>s</sub> (T<sub>s</sub> = 1/f<sub>s</sub>). The reference signal may be generated from three separate phase references using the [[Alpha beta gamma transform\|~~<math>\alpha\beta\gamma</math>~~αβγ transform]]. The reference vector is then synthesized using a combination of the two adjacent active switching vectors and one or both of the zero vectors. Various strategies of selecting the order of the vectors and which zero vector(s) to use exist. Strategy selection will affect the harmonic content and the {{ill\|switching loss\|lt=switching losses\|de\|Schaltverluste}}.
