From dq to abc
WebJun 24, 2024 · The “dq0 to abc” block computes a three-phase ( abc) signal from a space vector in a rotating reference frame ( dq0 ). The angle of the rotating reference frame is given by the second input θ = ω t. The transformation is performed by applying successively a dq0 to alpha-beta-0, and an alpha-beta-0 to abc transformation: WebJul 12, 2024 · This work proposes a novel methodology to modify the way in which the computations of the abc–dq–abc transformation are performed to avoid the use of trigonometric calculations with the objective of reducing the computational burden and time when implemented in digital signal processing hardware.
