Clarke Transform

Category: Toolbox > eDrives and Systems > eMotors > Other Tools > Transforms  

Description: The Clarke Transform block performs a Clarke forward transform (2 X 2).

The Clarke Transform block provides a magnitude invariant transformation of three-phase signals/systems, components [a b] to orthogonal reference frame components [alpha beta]. This Clarke transformation is specific to the case where the primary axis of the three-phase coordinate system is aligned with the primary axis of the orthogonal coordinate system.

The transform is given by:
