摘要
对半导体开关在这种超限条件下的单次使用情况进行了研究,尤其对级联状态多次试验。试验结果显示,额定电流为30 mA的半导体开关可以实现单次放电电流达到10 kA的稳定放电。通过对放电过程进行分析发现,开关从导通至最终损坏经过了一个比较复杂的物理过程,电路拓扑结构及其开关安装位置都将会对输出性能产生影响。
Abstract
The single use of semiconductor switches in some special conditions was studied, especially in the cascade tests. The results show that the switch whose rated current is 30 mA can achieve a stable single discharge with a current of 10 kA. The discharge process was also analyzed. The switch experiences a complicated physical process from conduction to final damage. The circuit topology and the switch installation position have an effect on the output performance.
