   Modulation Strategy Impact of BEV Inverters on the Voltage Ripple and the High-Voltage Traction System Stability
By Cornelius RETTNER [View]
[Download]

Abstract: Modulation strategies of traction inverters have a high impact on the efficiency and voltage utilizationof the electric drivetrain. An often underestimated effect that comes along with various modulationstrategies is their diverging impact on the resulting voltage ripple within the High-Voltage (HV)traction system. The voltage ripple in the first place, but also the DC-side current ripple can beconsidered as the stability criteria of a HV traction system, which depend upon the DC-link currentand the HV system impedance. Since the voltage ripple is the main DC-link capacitance design requirement, the DC-link current harmonics of each modulation strategy have to be analyzed in detail as well as their application range within the torque-speed diagram of an electric drive. The target is to design an ideal DC-link capacitance for each inverter within an electric platform. Therefore, we will discuss the challenge of combining the voltage ripple requirement of different modulation strategies with various HV traction systems.

Abstract: Regulations demanding reduction of CO2 and other greenhouse gas emissions are being implementedworldwide and they are the main driver for electrification in transportation. This presentation focuseson the trends of electric powertrain for trucks, their configuration in the vehicle, their limitations andoptimization potential.

   Zero Emission Trucks & Bodies
By Martin GLASER [View]
[Download]

Abstract: The commercial vehicle business is facing a major transformation into zero emission transportation. The presentation is about the different challenges and their possible solutions in terms of alternative powertrains for heavy duty trucks and the approach which Daimler Truck is following. Furthermore, the specifics for truck manufacturer in Power Electronics Systems will be lined out. In some applications the body of the truck has a higher energy demand as the truck itself, e.g. construction site vehicles like concrete pumps. Some ideas about different approaches will be shared as well.
