目前机载火控装置发展迅速,相应出现了多种速率敏感元件——速率陀螺等.为满足火控需要,就必须研制多种机载火控电源.该电源工作条件恶劣:振动、冲击强烈、环境温度变化大(-55℃～+60℃).同时要求电源本身体积小、重量轻、耗电少.因此所用元器件要性能稳定,工作可靠.此外,还必须具备振荡源频率稳定,精度高,性能好.两相马达电压相位差要恒定等.这里所设计的电源指标为:同步器电源;Uc=7V±0.3%,i(?)150mA,f=1600HZ±0.1HZ.失真度:α(?)3%的正弦波电压.两相马达电源:U_A=U_B=24V±IV,
At present, the rapid development of airborne fire control devices, corresponding to a variety of rate-sensitive components - rate gyro, etc. In order to meet the fire control needs, we must develop a variety of airborne fire control power supply. The power of poor working conditions: vibration, impact , Ambient temperature changes (-55 ℃ ~ +60 ℃). At the same time require the power itself is small, light weight, low power consumption. Therefore, the components used to stable performance, reliable work. In addition, you must also have the oscillation frequency stable, High precision, good performance. Two-phase motor voltage phase difference to be constant, etc. Power indicators designed here are: Synchronizer power supply; Uc = 7V ± 0.3%, i (?) 150mA, f = 1600HZ ± 0.1HZ. Distortion : α (?) 3% sine wave voltage Two-phase motor power supply: U_A = U_B = 24V ± IV,
