Foundations of Magnetics for Power Electronic Converters

Every efficient power converter relies on well-designed magnetic components, yet inductors and transformers are often the most misunderstood parts of a circuit. Understanding the physical principles of magnetism is essential for creating reliable, high-performance power electronics. This text-based course guides you from the fundamental physics of electromagnetism to the practical design of custom magnetic components. You will gain the confidence to select the right core materials, calculate winding losses, and optimize inductors and transformers for modern power applications. What you'll learn: - Understand foundational magnetic concepts including reluctance, inductance, flux density, and core saturation. - Analyze energy storage mechanisms within magnetic cores and air gaps. - Design practical inductors and transformers using systematic core-selection methodologies. - Calculate winding losses, taking into account skin and proximity effects at high frequencies. - Evaluate modern magnetic materials and their compatibility with high-frequency wide-bandgap semiconductor technologies. The course begins with essential electromagnetic theory and core material characteristics before moving step-by-step through practical design procedures, thermal considerations, and loss analysis. You will consolidate your learning through clear written explanations, practical formulas, and comprehensive design exercises. This course is designed for electrical engineering students, hobbyists, and practicing engineers looking for a solid foundation in magnetics. No advanced background in power electronics is required to begin. Start reading today to master the core principles of magnetic component design.
