Multi-winding double-salient-pole generator and output transformation and control device

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of aviation ground support, in particular to a multi-winding double-salient pole generator and an output conversion and control device, which are used for ground electric starting and ground power inspection of aircraft and aircraft to ensure power supply. Background technique [0002] The electric excitation doubly salient generator is based on the permanent magnet doubly salient motor, and uses the excitation winding instead of the permanent magnet of the original motor as the excitation mechanism. The structure and manufacturing process of the motor are very simple, with high reliability and low cost, and are especially suitable for high-speed operation. When the motor is used as a motor, it has the advantages of high operating efficiency of a DC motor, good speed regulation performance, and convenient four-quadrant operation; when it is used as a generator, it does not need a position sensor, and the out...
