摘　　要：目前真空触发开关(TVS)触发源技术多为脉冲变压器或者汽车点火线圈作为触发能量转换器件,该触发源的特点是触发可靠、装置简单,但由于存在能量损耗,触发电压陡度不高,导通时延和陡度较大,触发准确度只能达到微秒级。对现有的触发回路进行改进,重新设计触发回路,对间接和直接触发方式的触发能量、导通时延和抖动分析。结果表明,直接触发优于间接触发,导通时延和抖动从μs级降为ns级。The triggered vacuum switch （TVS） is used to the impulse or auto ignition loops as the technology of the triggering origin at present. The triggering origin is easy and credible, but because there is the energy wastage, the gradient of the triggering voltage is not high and the switching delay time is greater. The accuracy is only microsecond. The triggering circuit is anew designed and the parameters are changed. The triggering circuit includes straight and separate triggers. The results show the straight trigger is better than separate trigger. The switching delay time and the jitter time are dropped from microsecond to nanosecond.
