An Analysis of GATs Compatibility Between High Current Gain and High Avalanche Breakdown Voltage

Abstract

【中文摘要】 通过作者最近建立的关于电力半导体器件 GAT的集电结耗尽层电位分析和电场分布的二维解析模型定量研究了 GAT的雪崩击穿特性 ,并且定量解释了该器件实现高击穿电压与高电流增益兼容的实验结果。 【英文摘要】 By the aid of the two dimensional analytical model [5] of the electric potential and field distribution in power semiconductor GATs collector depletion space in a cut off state which was established by the writers lately,the GATs avalanche breakdown characteristics was investigated quantitatively,and the experimental results which concluded that the GATs can realize the compatibility between high breakdown voltage and high current gain,were...国家自然科学基金!( No.69896260-06 );国家高技术研究发展计划( 863-715-010
