Abstract

Factors affecting the distribution of direct current among parallel transistor chips in a multichip IGBT module are experimentally investigated. The voltage-current characteristics (VCCs) of single-chip modules with the rated operating current equal to 200 A and voltage equal to 1200 V in the collector current range from 50 to 200 A at temperatures equal to 25, 90, 120 and 150°C were measured to evaluate the compensation ability of the saturation voltage positive temperature dependence.

A comparative experiment on measuring the voltage drop across individual parts of the conductors system composed of samples of IGBT modules with different topologies based on the half-bridge circuit arrangement and having three parallel-connected chips in passing a 400 A direct current through the module was carried out. It has been found from the experimental results that the use of the saturation voltage positive temperature dependence for equalizing the current distribution between the chips has limited capabilities, and that one of possible methods for achieving this is to use the resistance of a system of aluminum conductors.

Comparative tests were carried out for estimating the stability of modules with different topologies to the effect of cyclic current load in a mode facilitating accelerated degradation of the soldered seam between the chip and the DBC substrate. The experimental results confirm the importance of considering the factors affecting the static current distribution between the chips in designing the topology of multichip IGBT modules.
