摘要
针对飞机直流电源系统中变压整流器多采用多台并联供电方式,负载电流不平衡的问题,本文通过分析变压整流器的供电特性,以变压整流器并联供电均衡性为中心,采用电路分析方法,研究了飞机变压整流器并联运行条件和负载分配规律。最后以变压整流器两类参数不等时的影响为例,分析了参数不等时的负载分配情形。分析结果表明:仅靠滤波器调节无法实现多台变压整流器的供电均衡,必须加自动均衡电路进行调节。
To the problem of unbalanced load current in aircraft DC power supply system for the transformer rectifier units with many sets of parallel power supply mode, this article through the analysis of the power supply characteristics of transformer rectifier, with rectifier power supply in parallel balance as the center, and the circuit analysis method, studied the aircraft transformer rectifier parallel operation conditions and the load distribution rule. Finally with transformer rectifier with two kinds of parameters as an example, the influence of load distribution of the parameter range is analyzed. The analysis results show that the adjustment cannot be achieved merely by filter more transformer rectifier power balance, and automatic balancing circuit must be regulated.
