| 摘 要： | 针对Trench gate/Field-stop IGBT结构特有的关断过程中集电极电流下降率不可控问题,引入了载流子抽取模型来模拟器件关断过程中的集电极电流下降阶段器件内部载流子的动态行为特性,并以此为基础分析了驱动器为适应Trench gate/Field-Stop IGBT结构这种关断特性而引入的有源箝位功能的作用机理,验证了载流子抽取模型在器件级与电路级交互作用分析中的实用性,为后续实现器件与电路的最佳匹配奠定了基础。

| Abstract: | Considering the collector current falling rate uncontrollability of Trench/Field-Stop IGBT modules, the carrier extraction model has been introduced to described the storage carrier dynamic behaviors during the collector current falling transition of the IGBT turn-off process. With this model, functional mechanisms of the Active Clamping circuit in IGBT drivers which is integrated to fit this special turn-off characteristic of the Trench/Field-Stop IGBT can be analyzed. |
