Description

This course provides an in-depth exploration of power converters specifically designed for Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs). With the growing demand for clean and efficient transportation, understanding how electrical energy is managed within these vehicles is essential. Power converters serve as critical components that control, regulate, and direct energy flow between key subsystems such as batteries, motors, and auxiliary electronics.The course begins by introducing the fundamentals of power converters, highlighting their essential role in EV and HEV architectures. Students will then study various power semiconductor devices—including MOSFETs, BJTs, TRIACs, and power diodes—that form the foundation of most converter circuits. Their characteristics, switching behavior, and application in vehicle systems will be discussed in detail.The curriculum is structured to cover practical converter applications such as:Controlled rectifier-fed DC drives for different load types (R and RL)Cycloconverter-fed AC drives using both step-up and step-down configurationsChopper-fed DC drives, exploring all five classes (A to E) with quadrant-based operationSpeed control techniques for three-phase induction motors through stator voltage variation and slip power recoveryIn addition, learners will engage in the design and simulation of DC-DC converters, including buck, boost, and buck-boost topologies, to understand voltage regulation for various vehicle loads. The course also emphasizes inverter functionality, explaining their operation in electric motor drives and their role in regenerative braking systems.Using hands-on simulation tools and practical case studies, students will develop skills to analyze and design efficient power conversion systems tailored for e-mobility.This course is ideal for students, researchers, and professionals in electrical, electronics, mechatronics, or automotive engineering who seek to build core competencies in EV power electronics and contribute to the future of sustainable transport.
