摘要
介绍了DC-DC变换器在飞机变频电源中的应用,根据飞机用电设备及供电系统的特点,提出了一种带有阻断电容的DC-DC全桥变换器,建立了它的静态模型。在分析了稳定性后,利用Saber软件对系统进行仿真,设计出一台15kW的实验样机,并给出相应的过压、过流保护电路。实验结果表明该电路工作原理正常,完全可以满足飞机供电的要求。
The application of DC-DC converter in the aircraft variable frequency power system was introduced.According to the characteristic of aircraft electrical load and power system,a kind of the full bridge DC-DC converter with a blocking capacitor was proposed and a static model was builded.A 15 kW prototype with protection function of over-voltage and over-current was designed based on analyzing the stability of the static model and simulation in Saber platform.After the analysis of perception and Labview measure system,the experimental results show that the design of the prototype is reasonable and can meet the requirements of the aircraft power system.
