The Modeling and Simulate for Aircraft Secondary Electric Power Supply Based on Saber

The aircraft secondary electric power supply is an important composition of aircraft power supply system. Its performance affects the reliability and safety of the aircraft. This paper introduced the function and loads of the secondary electric power system and established the models of three-phase static inverter, DC-DC converter, over-current protection and steering engine in Saber firstly. Through simulation experiment, the results reached the system function requirement. The experiment showed the feasibility and effectiveness of the modeling methods.
