Research on adaptability of fastening force for 6-inch IGCTs
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 6 000 A/4 500 V reverse blocking IGCT as an example, the influence of the fasteni...

| Summary: | 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 6 000 A/4 500 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 improved by more than 20%. |
