摘要
IGCT作为一种高功率等级的全控型压接器件,随着器件直径扩大及应用串压级数增加,紧固力的设计至关重要。文章以6英寸6 000 A/4 500 V逆阻型IGCT器件为例,分析紧固力不均造成的器件性能影响,并优化IGCT阴极梳条局部跨距和采用边缘门极结构设计。试验结果表明,优化设计的器件在额定紧固力范围内不再出现门阴极性能异常,且紧固力适应性提升20%以上。
As a high-power fully controlled press-pack device,IGCT's design of fastening force is crucial for its characteristics with the expansion of device diameter and the increase of cascade devices.Taking the 6-inch 6000 A/4500 V reverse blocking IGCT as an example,the influence of the fastening force on the device performance was analyzed,the design of local space between IGCT cathode comb bar was optimized and the edge gate design for IGCT chips was adopted.The experiment results show that the optimized device no longer has abnormal gate cathode performance within the rated fastening force range,and the adaptability of the fastening force is im‐proved by more than 20%.
