Electric Propulsion Drive Trains – High Efficient and Robust Electric Propulsion Drives

The objective of the working package 2 of the eMOTION Interreg project is the optimization of the efficiency and of the robustness of electric propulsion drive trains of electric vehicles. Different methodologies for the optimization are investigated and analyzed theoretically and by simulation. The focus of the optimization is based on the power electronics which interfaces the battery and the AC drive motor. [read more]Besides the mandatory DC-AC inverter, the application of an additional DC-DC converter is investigated. For the DC-AC inverter different topologies are analyzed and compared regarding the overall output performance. In the laboratory, the different optimization methods will be realized and verified at a 20 kW laboratory setup.
