Study oncharge and discharge of supercapacitor in thyristor trigger

供电电源是脉冲功率系统晶闸管触发装置的关键组成部分。基于大功率晶闸管的触发要求,对触发电路进行了方案设计。系统采用了超级电容器作为供电电源来满足触发电路的供电电压要求。在此进行多次晶闸管触发实验,反复试验多组不同容量的超级电容器的充放电特性,选择容量合适的超级电容器作为晶闸管触发电路的触发电源。实验结果表明,晶闸管触发装置能够可靠触发,设计满足实验要求;选择5组超级电容器供电,满足触发时间要求。

Power supply is a key component of thyristor triggering devices for pulsed power systems. Based on the triggering requirements of high power thyristor, the trigger circuit is designed. The system use super capacitor as a power supply to meet the trigger circuit power supply voltage requirements. To carry out multiple thyristor trigger test, in order to obtain the super capacitor charge and discharge characteristics, repeatedly test multiple sets of different capacity, and select the appropriate capacity of the trigger power. The experimental results show that the trigger device can be reliably triggered to meet the design requirements; select five groups of super capacitor power supply to meet the trigger time requirements.
