In the realm of power electronics, the design and analysis of magnetic components like inductors and transformers are paramount. For anyone looking to truly understand these critical elements, the Coursera course ‘Magnetics for Power Electronic Converters’ from CU Boulder is an absolute must-take. This course, which can even count towards a Master’s in Electrical Engineering, provides a comprehensive journey into the heart of magnetic design.
The course kicks off with a solid foundation in ‘Basic Magnetics.’ It meticulously reviews fundamental magnetic circuit theory, inductor modeling, and transformer modeling. This initial module is crucial, equipping learners with the theoretical tools necessary to grasp the operational principles of magnetic devices, accurately model their losses, and ultimately, design them effectively for switching converters. It emphasizes that magnetic design cannot be a separate entity but must be integrated with the overall converter design.
Moving into the practical challenges, the course dedicates a module to ‘AC Copper Losses.’ Here, you’ll delve into the often-overlooked phenomenon of eddy currents within winding conductors. It clearly explains how effects like the ‘skin effect’ and ‘proximity effect’ can significantly increase copper losses beyond what DC resistance would suggest. This is particularly relevant for high-current, high-frequency applications, and the module provides actionable methods for calculating these losses.
The ‘Inductor Design’ section is where theory meets practice. You’ll learn to design inductors for switching converters using the Geometric Constant (Kg) method. The focus is on achieving a specified copper loss while adhering to a maximum flux density (Bmax). The course thoughtfully covers both simple single-winding inductors and more complex multi-winding components like coupled inductors and flyback transformers.
Finally, the ‘Transformer Design’ module tackles scenarios where core losses, rather than saturation, limit performance. It highlights the importance of minimizing total losses by finding the optimal AC flux density for devices like high-frequency transformers. Through detailed design examples, such as isolation transformers for full-bridge converters and isolated Cuk converters, the course solidifies your understanding of how to design for minimized total core and copper loss.
Overall, ‘Magnetics for Power Electronic Converters’ is an exceptionally well-structured and informative course. It bridges the gap between theoretical physics and practical engineering design, making complex magnetic concepts accessible. Whether you’re a student, a researcher, or a practicing power electronics engineer, this course is highly recommended for anyone serious about designing efficient and reliable power converters.
