Information

The function j_abc(u) is a rotation of u by +90 degrees around the axis {1,1,1}.

The notation is chosen in analogy to the expression

  j*omega*u

  j: imaginary unit
 (omega: angular frequency)
  u: complex vector (voltage or current).

The matrix expression corresponding to

  j*u

  J_abc*u = ([0,-1,1; 1,0,-1; -1,1,0]/sqrt(3))*u
