Embodiment Construction

[0021] In order to meet the high-power AC and DC power requirements required for the current aircraft ground starting power supply and aircraft ground inspection, the generator is required to provide a high-voltage DC power supply capable of 28.5V, 28.5V / 57V, 0-70V, 270V, 115V / 200V , 400HZ three-phase intermediate frequency and 220V / 380V, 50HZ three-phase power frequency AC power multi-functional aviation ground power supply. In order to achieve the above purpose, it needs to be realized from the following three parts: 1) Power generation system: in the multi-winding technology in DSEG, the composition and structure of the high-voltage winding and the composition and structure of the low-voltage winding are studied. 2) Power supply system: connection of high and low voltage winding output circuits and power conversion circuit. 3) Control system: apply DSP to realize the control of 28.5V, 28.5V / 57V, 0-70V, 270V high-voltage DC power supply, 115V / 200V, 400HZ three-phase medium f...

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...
