Switched-Mode Converter Circuits and Power Semiconductors

Designing efficient power electronics requires a deep understanding of how switches, diodes, and transistors behave in transition. This course provides a clear, text-based foundation in switched-mode converter circuits and the semiconductor devices that drive them. You will transition from basic circuit analysis to modeling real-world converter behaviors, understanding bidirectional power flow, and accounting for switching losses. Through clear written explanations and step-by-step mathematical derivations, you will learn how to select and model key components for modern power systems. What you'll learn: - Understand the fundamental operating principles of switched-mode power converters and bidirectional power flow. - Analyze the characteristics and switching times of power diodes, power MOSFETs, and IGBTs. - Refine equivalent circuit models to incorporate non-ideal semiconductor behaviors and conduction losses. - Evaluate modern wide-bandgap (WBG) semiconductor materials like Silicon Carbide (SiC) and Gallium Nitride (GaN). - Calculate switching losses and efficiency metrics for various converter topologies. The journey begins with the core terminology of switching converters before moving into detailed device physics and circuit modeling. You will progress through practical analysis of loss mechanisms, thermal considerations, and advanced bidirectional topologies. This course is designed for engineering students, hobbyists, and practicing technicians looking to build a strong foundational understanding of power electronics. No advanced background in power design is required, though a basic familiarity with introductory circuit theory is helpful.
