WebMay 26, 2015 · The fundamental reason to transform the three-phase instantaneous voltages and currents into the synchronously rotating reference dqo frame is to make … WebDeduce the dq0 components from the abc signals by performing an abc to αβ0 Clarke transformation in a fixed reference frame. Then perform an αβ0 to dq0 transformation in a rotating reference frame, that is, by performing a −(ω.t) rotation on the space vector Us = u α + j· u β.. The abc-to-dq0 transformation depends on the dq frame alignment at t = 0.
