2.1.4 Inverse Clarke Transformation
The Inverse Clarke Transformation transforms electrical signals from the stationary two axis orthogonal reference frame (αβ) to the three axis reference frame (abc) as shown in the following figure.
The transform is expressed by the following equations:
Where:
Uα and Uβ are the two-phase orthogonal voltages in the αβ reference frame, Ua, Ub, and Uc are the three-phase voltages in the abc reference frame.
