**Description:** The Inverse Park Transform block
transforms direct and quadrature signals [d q] to orthogonal components [alpha
beta] given a particular rotation angle, θ.

Park’s Inverse Transform is defined as:

**Diagram name: **Inverse Park 3P Modulation

**Location: **Examples > eDrives and Systems >

The following diagram uses Park’s and Clarke’s inverse transforms to create a three-phase modulated signal at a specified rotation frequency (20 rad/sec). The input signal defines the envelope of the modulated signal and the angle rate defines the three-phase frequency.
