Power electronic converters play a crucial role in integrating renewable energy systems into the power grid. This course focuses on the basic operating principles of grid-connected converters. It begins with an introduction to the switching pole, the fundamental building block of a grid-connected converter, and analyzes its operation under square-wave and sinusoidal pulse-width modulation. The commonly used single-phase and three-phase converter topologies are then introduced and analyzed using the switching pole as the unifying framework. The space vector modulation technique for three-phase converters is also covered. Together, these concepts lay the essential foundation for understanding the modeling and control of grid-connected converters, which are addressed in the follow-up course.

Intended audience: Third and Final Year UG students in Electrical/Electrical and Electronics Engineering, PG and PhD Students who (wish to) specialize in Power Electronics and Power Systems

Prerequisites: Anyone who has done some UG level courses related to circuit analysis, basic control systems and introductory power electronics can opt for this course.
