陀螺仪是飞机惯性导航系统的重要部件,它的精度直接影响着整个惯性导航系统的精度。文章针对陀螺仪电机驱动电源的要求,设计了一种电压型SPWM逆变电源,给出了电源系统的主电路和控制电路,同时设计了逆变电源的滤波电路,该电源系统可以给陀螺仪提供高质量的电能。通过saber软件进行了仿真实验,实验证明该驱动电源具有精确度高、效率高等特点。
Gyroscope is an important part of the aircraft inertial navigation system, its accuracy directly affects the accuracy of the entire inertial navigation system. In order to meet the requirement of gyro motor drive power supply, a voltage type SPWM inverter power supply is designed. The main circuit and control circuit of the power supply system are given. At the same time, the filter circuit of inverter power supply is designed. The power supply system can give gyro Provide high quality electric energy The simulation experiment was carried out by saber software, the experiment proved that the drive power has the characteristics of high accuracy and high efficiency.
