摘　　要：为增加供电功率和供电可靠性,现代飞机通常采用两台或多台变压整流器并联供电的方式,但并联供电难以实现供电均衡。文中通过分析变压整流器的供电特性,研究负载均衡供电条件及负载分配规律,对变压整流器任一参数差异对均衡电流差的影响做了推导计算,分析了参数不等时的负载分配情形。研究结果表明:并联的变压整流器要实现供电均衡,对其相似性要求高,其主要参数要完全相等,任一参数不等就会导致供电失衡。To increase the power supply and power supply reliability, modern aircraft usually takes two or more transformer rectifier power supply in parallel, but which can＇t realize the balance of power supply in parallel. Based on the analysis of transformer rectifier power supply characteristics, the research of load balancing power supply conditions and load distribution rule, the difference in parameter of a transformer rectifier any effect on the balance differential current is calculated, and analyzed the load distribution of the parameter range. The results show that the parallel transformer rectifier to realize power balance, the similarity requirement is high, the main parameters to fully equal, any parameter range will lead to the power supply imbalance.
