Engineering Application Research of Aircraft Power Supply Characteristics Based on 18-Pulse Rectifier Power System

Abstract

The low-harmonic and high-power density multi-pulse autotransformer has many advantages, such as simple structure, high reliability, high efficiency, strong overload ability, and so on. Therefore, it has a broad application prospect in aviation field. The multi-pulse rectifier power system is more and more widely used in aerospace. However, there are many practical engineering problems of the aircraft power supply characteristics that are difficult to predict. In this paper, the aircraft power supply characteristics of the rectified power system with 18-pulse autotransformer rectifier are simulated and investigated. According to the handbook MIL-HDBK-704-3, the performance of the power supply in the normal, abnormal, and fault state is verified and tested in detail. The research and discussion are carried out from six aspects: the load measurement, the steady-state limits, the voltage phase difference, the voltage transient, the frequency transient, and the power failure. The system can meet the requirements of the U.S. military standard MIL-STD-704A for the aircraft power supply characteristics. It has been applied to the radar power supply system of a large transporter, and the conformance verification test of the aircraft power supply characteristics has been completed, which provides the practical application basis for the engineering realization of the multi-pulse rectifier power supply in the radar power supply system. It also provides a reference for the development of the power supply system for other aircraft.

Pulse Tripling Circuit and Twelve Pulse Rectifier Combination for Sinusoidal Input Current

“…In recent years, different structures of multipulse rectifiers have been designed and employed in order to improve the power quality at the common point of connection in industrial applications such as power system, ship propulsion and aircraft electricity system as well as high voltage DC transmission lines. Multipulse rectifiers (MPRs) have widely been used in industry due to their low harmonic distortion, simple configuration, robustness and also power factor correction [1][2][3]. Although, various structures of 12-and 18-pulse rectifiers have been introduced, developed and utilized to reduce the harmonic content of the line current [4][5][6]; but still these structures could not satisfy and meet the standards requirements and recommendations [7][8][9][10].…”

Novel Step-Up Topologies of Zigzag Autotransformer

“…Scholars have successively studied 12, 18, 24 and 36 pulse phase-shifting rectification technology [6][7][8][9]. The theory of 12 pulse rectification has developed for a long time and plays an irreplaceable role in the field of multi-pulse basic research [10][11][12].…”

Multi-Phase Shifting Autotransformer Based Rectifier

“…MPRs have been widely used in industry due to their low harmonic distortion, simple configuration, robustness and also power factor correction [1]- [3]. Although, various structures of 12-, 18-pulse and 20-pulse rectifiers have been introduced, developed and utilized to reduce the harmonic content of the line current [4]- [6], [11], [12]; but still these structures cannot satisfy and meet the standards requirement [7], [8]. Increasing the number of pulses in MPRs using multiple output phases of the phase shift transformers is considered as one of the main solutions to improve power quality factors.…”
