为了研究航空变频电源对自耦变压整流器的影响,提出了一种分析方法:输入采用频率可调的交流电源,连接自耦变压整流器。通过变化负载参数,在变频电源供电时,测量自耦变压整流器的移相波形、直流母线电压波形、输入功率、功率因数和效率等重要参数。使用仿真模型初步实现了该分析方法的仿真验证,并基于测试平台搭建自耦变压器样机。实验结果表明,该研究为使用变频电源的自耦变压整流器的设计提供了技术支持。

In order to study the influence of Aeronautic Variable-frequency power on the ATRU,an analytical method is proposed,which uses a frequency adjustable AC power source to connect the ATRU.By changing the load parameters,the phase shift waveform,DC bus voltage waveform,input power,power factor and efficiency of the ATRU are measured when the variable-frequency power supply is supplied.The simulation model is used to realize the verification of the analysis method,and the prototype of the ATRU is built based on the test platform.The experimental results show that the research provides technical support for the design of ATRU.
