Switched Mode Power Conversion

This course introduces students to the fundamentals of power electronics with a clear focus on understanding, designing, and controlling switching power converters. It begins with an explanation of switching devices, comparing ideal and practical behavior, and covers their control, gate drive circuits, and protection methods to ensure safe operation. The course then explains reactive elements such as inductors and capacitors, including how to select and design them for power electronic circuits. Various switching power converter topologies are studied in detail, along with their working principles and steady-state operation. Students learn how to develop steady-state and dynamic models of converters for analysis and design. The performance of converters, including efficiency, regulation, and response, is thoroughly discussed. A review of linear control theory is provided to build a foundation for control applications. The course then focuses on closed-loop control of power converters to achieve stable and accurate output. Practical design considerations are emphasized throughout the course. Finally, students apply their knowledge through sample designs and construction-based projects, helping them connect theory with real-world applications.
