A poly phase transformer design is presented in which
transformer output pores 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 phases.
The main transformer permits rough phase adjustment to be
made with the auxiliary transform permitting phase 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.
