Problems solved by technology

The high-power IGBT module of the existing design needs to connect the IGBT chips in parallel on the copper-clad ceramic substrate (DBC). Uneven current, which leads to the problem of lower module reliability, so the existing simple multi-chip parallel scheme cannot achieve the purpose of increasing the power of IGBT modules

Abstract

The invention discloses an IGBT (Insulated Gate Bipolar Translator) module which comprises a base plate, a plurality of IGBT chips and at least one backward diode arranged on the base plate and a first conducting connection plate and a second conducting connection plate arranged on the base plate, wherein the first conducting connection plate and the second conducting connection plate are electrically connected with each IGBT chip and the positive pole and the negative pole of the backward diode respectively and correspondingly so as to be connected with the IGBT chips and the backward diode in parallel, and preset positions between both ends of the first conducting connection plate and between both ends of the second conducting connection plate are respectively provided with an electrode leading-out part so as to lead out an installation electrode of the IGBT module. The invention can enable the IGBT module to provide large power with high reliability.

Description

technical field [0001] The invention relates to an insulated gate bipolar power tube (IGBT), in particular to a high-power IGBT module. Background technique [0002] As the application range of the insulated gate bipolar power tube (IGBT, Insulated Gate Bipolar Transistor) module is getting wider and wider, the power requirements for IGBT applications are also getting higher and higher. The size requirements of the package are getting higher and higher, so it is necessary to design a high-power ultra-compact IGBT module. [0003] At present, the highest current level of an IGBT single chip is 150A. To obtain a high-power IGBT module, a method of parallel connection of multiple IGBT chips must be used. The high-power IGBT module of the existing design needs to connect the IGBT chips in parallel on the copper-clad ceramic substrate (DBC). Uneven current, which leads to the problem of module reliability reduction, so the existing simple multi-chip parallel scheme cannot achie...
