级联型航空静止变流器直流环节电路拓扑研究

摘要：基于级联技术的新型航空静止变流器的效率主要取决于其直流变换环节。针对低压大电流应用,推挽正激变换器具有防止开关管的电压尖峰和抑制变压器偏磁等特点。本文详细分析了推挽正激变换器的工作原理，对比研究了该变换器的三种次级整流结构，比较了各自的优缺点。实验表明，采用全波整流的推挽正激变换器效率可以达到89%以上，为新型航空静止变流器效率超过85%奠定了基础。 叙词：静止变流器；推挽正激变换器；全桥整流；全波整流；倍流整流 Abstract：The efficiency of a novel aircraft static inverter based on cascaded inverter is mainly rested with its DC link. The push-pull forward converter has the advantages of preventing the high voltage spike of the switches and restraining magnetism deflection of the transformer in low-voltage high-current situation. In this paper, the principle of push-pull forward converter is analyzed in detail, three secondary-side rectifier topologies are studies contrastively and the advantages and disadvantages are compared. Finally, experimental results show that the efficiency of push-pull forward converter with full-wave rectifier is over 89%, which establishes the foundation of the novel aircraft static inverter’s efficiency exceeding 85%.
