摘要: 本文分析了GTO的关断原理,研究了GTO的参数设计和制作工艺。测试了GTO的掺杂分布和工作特性。采用国产材料和设备试制成500A逆阻型大容量GTO。其工艺可用于GTO的批量化生产。Abstract: Based on GTO s turn-off theory, parameter design and production technology are studied. Its performance characteristic and doping profile are measured. A 500 A reverse-blocked power GTO is made by using domestic material, equipment and installatiins. The technological process can be applied to the mass production of GTO.
