Abstract

The invention provides an IGCT packaging structure, which includes a ring-shaped gate, a connecting part, an elastic supporting part and an external connection ring of the gate. Wherein, the top and the bottom of the connection part are respectively connected with the ring-shaped gate electrode and the outer ring of the gate electrode, and the elastic supporting part is located in the connection part. The IGCT packaging structure provided by the present invention can simplify the packaging process while ensuring uniform pressure transmission, improve packaging efficiency, and effectively shorten the detour length of the commutation circuit, thereby effectively reducing the IGCT packaging structure of the stray inductance of the commutation circuit.

Description

technical field [0001] The invention relates to the technical field of IGCT packaging, in particular to an IGCT packaging structure. Background technique [0002] In the IGCT (Integrated Cate-Commutated Thyristor) package structure in the prior art, the disc spring is located close to the center of the IGCT package structure. During the packaging process, one end of the gate external ring needs to be bent upward to complete the installation of the disc spring. The disc spring After the installation is completed, the gate outer ring needs to be reset to ensure contact with the ring gate. Therefore, there are problems of uneven pressure transmission and complicated packaging process, and at the same time, there is also the problem of long detour length of the commutation circuit, resulting in more stray inductance. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, provide a method...
