基于电容损耗角等效模型的触发开关储能电路分析

某机械式常闭型触发开关广泛应用于空空导弹引战系统中,该触发开关储能电路由电阻器与电容器组成。在实际应用中,电容器并非一个纯电容,还存在串联等效电阻,用损耗角正切值表示。本文通过建立电容损耗角等效模型,运用MATLAB仿真,对触发开关储能电路进行建模,分析损耗角变化对电路影响。

Energy Storage Circuit of Triggered Switch Based on Models of Loss Angle on Capacitance

The mechanical closed triggered switch whose energy storage circuit consists of resistance and capacitance is widely used in Air-to-Air Missile Fuze-Warhead Systems.Actually,the capacitance isn’t a pure capacitance.The equivalence of series-wound resistances is included and it is denoted as loss angle tan δ.Based on the equivalence model of loss angle on capacitance and Matlab simulation,the energy storage circuit of triggered switch is modeled,and the influence of circuit by the changes of loss angle is analyzed.
