【摘要】 为了改善电感储能脉冲功率源的输出波形,本文提出一种基于电爆炸金属丝断路开关的方波输出脉冲功率源。该脉冲源以脉冲电容器为初始储能源,通过脉冲形成网络对电爆炸金属丝开关放电,当电流达到峰值附近时,电爆炸金属丝开关断开,将能量切换到负载上。由于脉冲形成网络中电感电流不能突变,所以负载上能得到数倍于初始储能电容充电电压的脉冲输出;由于脉冲形成网络中电容的续流作用,所以负载上能得到准方波脉冲输出.验证实验结果表明:在1μF初始充电电容充电32k V时,在10Ω负载上得到电压幅值83k V,半高宽279ns,90%平顶172ns左右的脉冲输出,证明了该原理的脉冲功率源可行性。更多还原

【Abstract】 In order to improve the output waveform of the inductive energy storage pulse power source, this paper presents a quasi-square wave output pulse power source based on electric explosive opening switch(EEOS). This kind of pulse source uses a pulse capacitor as the initial energy storage, which discharges to the EEOS through the pulse forming network(PFN). The EEOS switches off when the discharge current nearly reaches the peak, thus the energy is switched to the load. Since the current in the PFN’s inductors can not be mutated, the load voltage can amount to several times the charging voltage of the storage capacitor. Due to the non-mutated voltages in the PFN’s capacitors, the load voltage can be quasi-square. Parameters of the EEOS and the age capacitor being charged to 32 k V, the voltage on the 10Ω load is obtained as 83 k V in amplitude, 279 ns in FWHM, and about 172 ns in full width at 90% magnitude, indicating that this kind of pulse power source is feasible.更多还原
