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:

Example

Diagram name: Inverse Park 3P Modulation

Location: Examples > eMotors > Transforms

The following example illustrates the use of Park’s and Clarke’s inverse transforms to create a 3-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 3-phase frequency.
