Abstract : A polyphase transformer design is presented in which transformers output phasors are accurately constructed in both voltage magnitude and relative phase angle. The design incorporates both main and auxiliary transformers that are used in unison to produce the accurately constructed phasors. The main transformer permits rough phasor adjustment to be made with the auxiliary transform permitting phasor fine tuning. Such a design is particularly suitable in transformer approaches that require output phases that are of a number not evenly divisible by three. (Author)
