Inverse Decoupled Transform (Six-Phase)
Implement dqz1z2o1o2 to abc and xyz transform
Simscape / Electrical / Control / Mathematical Transforms
The Inverse Decoupled Transform (Six-Phase) block converts the direct, quadrature, z1, z2, o1, and o2 components in a rotating reference frame to the components of a six-phase system in the abc and xyz reference frame. The three-phase systems abc and xyz are spatially shifted by 30 electrical degrees.
You can configure the block to align the phase a-axis of the five-phase system to either the d-axis or q-axis of the rotating reference frame at time t = 0.
θ = ωt + Offset is the angle between the a and q axes for the q-axis alignment or the angle between the a and d axes for the d-axis alignment, where:
ω is the rotational speed of the rotational reference frame.
t is the time, in s, from the initial alignment.
The Inverse Decoupled Transform (Six-Phase) block implements the transform as
The z1–z2 and o1–o2 pairs do not form a rotating magnetic potential. They are generalized zero-sequence components.
