触发预电离一体化脉冲氙灯电源设计

采用高压触发预电离为一体+脉冲形成网络触发氙灯的技术路线,分别设计了脉冲氙灯电源系统中高压触发、预燃电流维持两个功能单元。根据脉冲氙灯160mm×9mm、极间距70mm的技术指标,成功设计了一台具有手动和电脉冲触发功能的方波脉冲氙灯电源。氙灯充电电压300~900V可调,光脉冲宽度为150μs±20μs,光脉冲上升时间不超过90μs,触发延迟不超过90μs,触发抖动在±2μs范围内。给出了单次触发情况下脉冲氙灯电源输出的实验结果,验证了所采用的设计原理和技术方法的可行性。

Design of xenon flash lamp supply adopting integrally triggering and pre-ionization

A new xenon flash lamp triggering method is discussed based on trigger and pre-ionization integrally. The pre-ionized lamp is lighted by high voltage trigger circuit, and the current is kept by pulse forming network for 150 s. A trigger power supply is designed for the xenon lamp with a length of 160 mm, a diameter of 9 mm and a gap of 70 mm. The pre-ionized voltage amplitude is 300-900 V, pulse width is 150 s20 s, raising-time is less than 90 s, trigger delay time is less than 90 s, and jitter time is less than 2 s. Experimental results has testified the feasibility of the design theory and method.
