Abstract

Abstract: Aiming at the inner design of the press-pack IGBT devices, this paper focuses on the study and optimal design of these issues, such as multi-chip pressure contact and its pressure balancing, internal current-sharing and current balancing among sub-units. Testing results showed that the developed press-pack IGBT devices has promising capabilities of current turn-off, short-circuit current and RBSOA, which indicates their good ability of inner current sharing.

Key words: current-sharing, press-pack, IGBT, design
