Advanced Power Electronics in Automotive Applications

It’s estimated that over 40% of the on-board components in the entire car are electronic based and that percentage is expected to rise with the growth of hybrid and autonomous vehicles and will continue to be an enabling technology for a wide range of future loads with new features and functions. From lighting, infotainment, and safety systems, to powertrain systems and beyond, power electronics has become one of the most important areas of the automotive subsystem and bringing this technology to non-electrical engineers will help bridge a knowledge gap that will drive teams forward quicker and more efficiently. This course builds on the SAE course, Introduction to Power Electronics and will delve deeper into key aspects of power electronic circuits, components and design requirements in automotive applications. Topics covered include power semiconductor devices, high-frequency magnetics and capacitors; their characteristics and operation, and their use in power electronics circuits. Advanced techniques for design, analysis, modeling, and verification of applied power electronics and related control systems for switch-mode power supplies, DC-DC converters, power rectifiers, static power inverters and universal power supplies are examined, along with electric machines, motors and transformers, and their associated power electronics drive requirements. The course also gives an overview of the electrical power system and power systems analysis in the context of power electronics applications in automotive platforms.
