The Choice of the IGBTs and their Cooling in Electric Traction Converters for Autonomous Vehicles

An important stage for the electric traction converters design is the choice of the power components and their cooling system. This paper is focused on the choice of the IGBT modules, their cooling and over-temperature protection in a test bench for electric traction converters designed for autonomous vehicles. Various possible applications on battery-powered vehicles together with their technical, functional characteristics and performances were taken into account in defining the parameters of the test bench, an important share belonging to the integrated Li-Ion battery propulsion/charging system developed by INDA. It is already used in the railway field on electric locomotives with batteries and in automotive on full electric trucks.
