Question
9 Phasor and space vector
A phasor is a complex variable of the form i, = Î, 20, = Î , e™ = i, cos 0, + j Î, sin, , where î, & o, are
the magnitude and phase angle, and j is the unit imaginary component. A space vector is a real variable of
the form I, =
, which is a 2-D Cartesian coordinate. Both Ï, & I, can be used to represent the same
quantity (think polar and Cartesian coordinates).
9.1
If i, = 5 4(-53.134"), what is I, ?
9.2
If I,
what is 7, ?
