3.1.1.1.1 (a, b)⇒(α,β) Clarke Transformation

The space vector can be reported in another reference frame with only two orthogonal axis called (α, β). Assuming that the axis a and the axis αlpha are in the same direction yields the vector diagram shown in Figure 3-4.

The projection that modifies the 3-phase system into the (α, β) 2-dimension orthogonal system is presented in Equation 18.

Equation 18. isα=iaisβ=13ia+23ib

The two phase (α, β) currents are still dependent on time and speed.
