| 摘 要： | IGCT单独使用时可以不用缓冲电路.但是6 kV及以上高压变频器需要将IGCT串联使用以获得更高的耐压水平.此时,IGCT需要并联缓冲电路才能安全工作.为设计6 kV高压变频器串联吸收电路,通过对IGCT特性进行分析,给出了设计IGCT缓冲电路的具体方法,通过试验验证吸收电路的工作效果.

| Abstract: | The single IGCT can work well without the snubber. However, two IGCTs are needed to connect in series when 6 kV medium voltage drive is developed. For the series connected IGCTs, the snubber is necessary. This paper analyzes the characteristics of IGCT and proposes some principles about the design of snubber. Finally, experiments are carried out to demonstrate the performances of the snubber. |
