Low-power Consumption Design for Small Calibre Induction Energy-storage Fuze

为解决某型小口径感应储能引信低功耗设计需求,充分利用感应电源能量,延长引信电路工作时间,分别从选用低功耗器件、降低供电电压、采用开关电源供电、降低系统工作频率、利用单片机节电工作模式以及合理处理单片机空余引脚方面,探讨了引信电路低功耗设计的方法,开展了相对应的原型样机实验.实验表明,选用25 V100μF钽电容器作为储能电容,在充满电的基础上,应用该低功耗设计方法,引信电路能够工作8 s以上,性能满足某型感应储能引信的技术要求.

In order to fully utilize the induction power,extend the fuze circuit working time and satisfy the requirement of low-power consumption design for a certain type of small calibre induction energy-storage fuze,the following design approaches were discussed: using the lower-power consumption IC devices,supplying lower voltage,using DC/DC power,reducing system frequency,utilizing single-chip power-saving mode and reasonably dealing with single-chip free-pin.The corresponding prototype experiment was carried ou...
