Web18 Jun 2024 · The paper proposes a generalization of the Park transform based on the Frenet frame, which is a special set of coordinates defined in differential geometry for space curves. The proposed geometric transform is first discussed for three dimensions, which correspond to the common three-phase circuits. Then, the expression of the time … Webto deﬁne the Frenet frame, a condition (a non-degenerate condition) is needed. In general, the parallel curve does not satisfy these conditions. It is well-known that the Bertrand curves of regular curves do not exist under a condition in [19, 21]. In [20], they consider the condition of the Mannheim curves of regular curves.
