Foundations of Power Electronics: Principles and Circuit Design

Power electronics is the backbone of modern energy systems, from the charger in your pocket to the grid-scale inverters of solar farms. Understanding how to control and convert electrical power efficiently is a critical skill for any aspiring electrical engineer. This text-based course guides you from the fundamental physics of semiconductor switches to the analysis and design of complex power converters. You will develop the analytical skills required to solve circuit equations, understand modern efficiency standards, and prepare for academic or professional engineering assessments. What you'll learn: Understand the foundational principles of power semiconductor devices, including diodes, BJTs, MOSFETs, and IGBTs; Analyze the operation of AC-DC rectifiers, DC-DC converters, and DC-AC inverters; Explore modern wide-bandgap semiconductors such as Silicon Carbide (SiC) and Gallium Nitride (GaN) and their role in high-efficiency designs; Calculate key performance parameters, including efficiency, total harmonic distortion, and power factor; Apply mathematical models and circuit analysis techniques to solve practical power conversion problems. The course begins with essential terminology, basic circuit laws, and semiconductor physics before advancing to converter topologies and control strategies. You will progress through detailed written explanations, step-by-step mathematical derivations, and targeted practice problems. This course is designed for undergraduate electrical engineering students, self-directed learners, and anyone preparing for foundational engineering exams. No prior advanced knowledge of power electronics is required, though a basic understanding of introductory circuit theory is helpful.
