The invention discloses a multi-winding double-salient-pole generator and an output transformation and control device, and particularly relates to an
aviation generator. A three-phase 12 / 8 pole single-winding double-salient-pole generator is adopted, and four sets of armature windings with three phases of A, B and C are wound on a
stator slot together; and (al1, bl1, cl1) and (al2, bl2, cl2) form two sets of low-
voltage three-phase windings, and (ah1, bh1, ch1) and (ah2, bh2, ch2) form two sets of high-
voltage three-phase windings, wherein (al1, al2, ah1 and ah2), (bl1, bl2, bh1 and bh2), and (cl1, cl2, ch1 and ch2) are placed in the same slot respectively, and each set of the windings and a power conversion device of each set of the windings form an independent generation channel. By using the multi-winding double-salient-pole generator and the output transformation and control device disclosed by the invention, 28.5V, 28.5V / 57V, 0-70V, 115V / 200V and 400Hz
intermediate frequency communications, and the output of a 270V high-
voltage direct current power supply are realized.
