Design of asymmetric 12-pulse auto-transformer rectifier unit

为满足多脉冲自耦变压整流器(ATRU, auto-transformer rectifier unit)小型化和轻量化的行业应用要求,本文提出一种不对称式12脉冲自耦变压整流器的设计方案。首先,详细阐述了其拓扑结构和绕组结构;其次,分析了输入电流谐波、等效容量等主要性能参数,并进行了Saber仿真验证;最后,在此基础上设计了10 kW自耦变压整流器样机,并对该样机进行了实测数据分析。分析结果表明,该设计方案满足DO-160标准,等效容量相比对称式12脉冲自耦变压整流器更小,更符合航空产品小型化、轻量化的设计需求。

To meet the industry application requirements of miniaturization and lightweight for multi pulse auto-transformer rectifier(ATRU),a design scheme of asymmetric 12-pulse ATRU was proposed in this paper.Firstly,the topology and winding structure were elaborated in detail.Secondly,the main performance parameters such as input current harmonics and equivalent capacity were analyzed and validated through Saber simulation.Finally,a 10 kW ATRU prototype was designed based on this,and the actual measured data analysis was conducted on the prototype.The analysis results showed that the design scheme can meet the requirement of DO-160 standard,and the equivalent capacity was smaller compared to that of symmetric 12-pulse ATRU,which was more in line with the design requirements of miniaturization and light weighting of aviation products.
