Research on the Ruggedized Multiplex Stabilized Voltage Supply for a Kind of Voltage Input at Super Wide Range

介绍一种新颖的可适应超宽范围电压输入的多路加固型稳压电源。在电源中,采用输入电压实时监控及自动切换技术、优化组合应用高频串联储能或开关稳压技术和低压差稳压技术、加固及电磁兼容设计技术,使电源对输入电压的适应能力达到了17(5.85V^41V),实现3U标准尺寸小型模块化插件式结构并能适应坦克、装甲等车载及舰载和航空航天等多种恶劣环境。

This paper introduces an originative ruggedized multiplex stabilized power supply that can be adapted for the voltage input at super wide range. The techniques of input voltage real-time monitoring and automatic switching are used in the power supply. The technique of high-frequency serial energy-accumulated switch stabilized voltage, the design of ruggedization and electromagnetic compatibility as well as the technique of low differential pressure stabilized voltage are optimized and combined together for application, enabling the adaptability of the power supply to the input voltage to be 1:7, implementing the miniature modular plug-in structure, and being adapted to various severe environments, such as vehicular (eg. tank, armored, etc.), shipborne, aviation, aerospace and so on.
