机载二次电源余度供电计时切换设计

机载二次电源是将主电源电能转换成另一种形式或规格的电能装置,用于满足不同机载用电设备的需要,是飞机电源系统的重要组成部分。根据机载二次电源具有的特点及功能要求,为解决二次电源供电出现掉电故障时,用电设备能及时有效地处理保存重要数据参数的问题,文中提出了一种根据实际使用要求,可调整参数满足不同处理数据所需时间的电路形式,能较为精准地满足计时供电要求。

Redundancy Power Interrupt Design for Airborne Secondary Power Supply

An important part of the aerocraft power supply system,the airborne secondary power supply is an electric equipment that changes primary power supply into another form or standard to satisfy the demand of different airborne electric equipments.For the airborne secondary power supply to handle and save the important data parameters timely and effectively in power down,this paper proposes a circuit according to actual user demands,adjusting the parameter to satisfy the time of different processing data to meet the power supply requirements precisely and timely.
