在航空变频电源供电的飞机上,自耦变压整流器(Auto Transformer Rectifier Units,简称ATRU)是一个重要设备,它的工作特性会受到电源频率的影响。论文通过仿真分析了ATRU的变压器在不同频率下的等效参数、输出电压、损耗等工作特性,接着分析了ATRU的输入电流谐波、输出电压与电源频率的关系,实验验证了仿真结果。该论文的研究成果为使用于变频电源的ATRU的设计提供了技术条件。
On an aircraft powered by aero-variable-frequency power, an Auto Transformer Rectifier Units (ATRU) is an important piece of equipment whose operating characteristics are affected by the power supply frequency. The thesis analyzes the ATRU transformers’ working parameters such as equivalent parameters, output voltage and loss under different frequencies by simulation, and then analyzes the relationship between input current harmonics, output voltage and power frequency of ATRU. The simulation results are verified by experiments. The research results of this paper provide the technical conditions for the design of ATRU used in variable frequency power supply.
