摘　　要：航空静止变流器是飞机上的重要电源设备,其功能是在飞机主电源失效时将低压直流电转变为交流电,以满足飞机应急状态下的交流用电需求,是飞机供电系统的最后一道“屏障”。通过分析航空静止变流器的结构及数学模型,建立了基于PSIM平台的仿真模型,并对DC/DC-DC/AC结构型的变流器进行了仿真分析。结果表明,该变流器在稳定性、抗冲击性和响应时间上都具有较大的优势,能满足飞机用电设备的电压要求。Aviation static converter is an important electrical power unit,and its function is to convert low-voltage DC power to AC power so as to meet the AC power demand of the aircraft in emergency when the main power supply of the aircraft fails,and it is the last“Barrier”of the aircraft power supply system.By analyzing the structure and mathematical model of aviation converter,a simulation model based on PSIM is established,and the DC/DC-DC/AC converter is simulated.The converter has great advantages in stability,shock resistance and response time,and can meet the voltage requirements of aircraft electrical equipment.
