Befordransföreläsning till adjungerad docent för Emad Samadaei

Welcome to the promotion lecture for Adjunct Associate Professor by Emad Samadaei from Volvo AB 

Topic: 
Power Electronics in Electric Vehicle: Technologies and Challenges
 
Short introduction:
Emad Samadaei is a Ph.D. holder in Power Electronics and currently works as the Group Manager and Product Owner of the Electric Motor Drive System at Volvo Group in Gothenburg, Sweden. His expertise includes power electronics, inverters, and electric drive systems, with significant contributions to the development of advanced power converters, inverter technologies, and integrated motor drive systems for commercial vehicles.

Summary: 
Power electronics play a critical role in the advancement of electric vehicles (EVs), enabling efficient energy conversion and management throughout the drivetrain. Key components include traction inverters, which convert DC power from the battery to AC for the motor, and DC-DC converters, which regulate voltage for auxiliary systems. Emerging technologies, such as Silicon Carbide (SiC) and Gallium Nitride (GaN) semiconductors, are enhancing efficiency, reducing energy losses, and enabling compact, high-performance designs.

However, challenges such as thermal management, cost, electromagnetic interference (EMI), reliability under extreme conditions, and functional safety concerns persist. In commercial vehicles, these challenges are amplified by higher power demands, heavier loads, and extended duty cycles, requiring robust solutions to ensure safe and reliable operation. Innovations such as integrated architectures (e.g., e-axles), advanced cooling systems, and enhanced safety mechanisms are addressing these challenges, driving the evolution of EV power electronics toward higher efficiency, reduced costs, and enhanced sustainability.

Welcome!
