and is illustrated in the following figure.
The inputs to this block are the phase a (
As) and phase b
Bs) components of the balanced three-phase quantities and the outputs
are the direct axis (
Alpha) component and the quadrature axis
Beta) of the transformed signal.
The instantaneous outputs are defined by the following equations and are shown in the following figure:
The variables used in the preceding equations and figures correspond to the variables on the block as shown in the following table:

To generate optimized code from this block, enable the
TI C28x (ISO) CRL.
The implementation of this block does not call the corresponding Texas Instruments library function during code generation. The TI function uses a global Q setting and the MathWorks® code used by this block dynamically adjusts the Q format based on the block input. See Using the IQmath Library for more information.
