用于飞行器姿态控制的脉喷发动机常采用火药包裹的桥丝电点火器进行点火，电点火器需要短时脉冲电流驱动。本文针对微小型桥丝电点火器驱动需求，设计了光耦隔离恒流源方式及电容储能脉冲放电驱动电路，均实现了对阻值波动桥丝电点火器的点火驱动。试验证明，光耦隔离恒流源方式可靠性高，安全稳定，电容储能放电方式效率高、作用迅速。该两种设计方法可为脉喷发动机的工程实践提供参考。

Pulse jet engines are often ignited by gunpowder wrapped bridge wire electric igniter and widely used in aircraft attitude control. The electric igniter needs short-pulse current driving for rapid initiation. In this paper,opto-isolated constant current source and capacitor discharge mode driving circuits are designed for the demand of micro-bridge wire electric igniter. Two kinds of detonating circuit designs implemente the ignition driving of brige wire e-lectric igniter wtih resistance fluctuations. The constant current source mode is capable of long storage life,compact spatial structure and high safety, and the reservoir capacitor mode demonstrates high energy efficiency and fast-acting for quick initiation. Two methods provide reference designs for the pulse jet engines of different engineering requirements.
