Low-power Consumption Design of Muzzle Inductive Setting Fuze Circuit

Based on analyzing the working principle of the muzzle inductive setting electronic time fuze, combining with the working characteristics of the inductive setting fuze circuit, the low-power- consumption circuit of the electronic time fuze is designed with the chip microcomputer. Some methods are used to reduce the power-consumption of the fuze circuit, such as lower supply voltage, interval power supply, on-line switching between an unattached high frequency clock and an unat tached lower frequency clock, software technique and so on. The power-consumption of the fuze is estimated by the working current, voltage and working time of every circuit module of the fuze. The result shows that the method meets the low-power-consumption designing requirements of the fuze circuit.
