**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:

The following diagram uses Park and Clarke 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.
