LinPak, a new low inductive phase-leg IGBT module with easy paralleling for high power density converter designs

Abstract:
In this paper, we present for the first time the LinPak, a new open standard IGBT module topology. The new phase-leg type module concept will be introduced first with a rating of 1700V and 2x1000A on a footprint of 100 x 140mm2 setting a new standard in power density. The proposed module though is designed to accommodate 1200V up to 3300V chip-sets and a 3300V version will follow soon after the presentation of the 1700V module. The new module features an exceptionally low stray inductance enabling the full utilization of advanced low switching loss IGBT chip-sets and even future full silicon carbide switch solutions. In addition the design is made for parallel connection with negligible de-rating in mind, thus a large range of inverter power can be realized with just one module type. Together with the open standard concept this module fulfills a long wish of the industry in nearly all high power segments such as traction/CAV, wind-power/solar and industrial drives to name a few.
