How magnetic circuit models reveal the hidden behavior of practical transformers

Lecture 10: Magnetics, Part 2 · 50:26 · Video: MIT OpenCourseWare · Watch at the source

In short: This lecture explains how to use magnetic circuit models to analyze transformers. By breaking down complex components into manageable concepts, it clarifies the roles of leakage and magnetizing inductances in real-world power electronics.

In this session of MIT's Power Electronics course, instructor David Perreault demonstrates how magnetic circuit modeling serves as a foundational tool for understanding transformer performance. The lecture focuses on translating physical magnetic structures into simplified circuit representations.

By applying these models, students can isolate and quantify the effects of magnetizing and leakage inductances. This approach is essential for engineers designing efficient power systems, as it provides a clear framework for predicting how transformers will behave under various operating conditions.
