Fundamentals of Transformers and Magnetic Circuits

This course covers the comprehensive understanding of electrical machines, with a primary focus on transformers and DC machines. For instance, it explains the structure and function of transformers, which consist of a magnetic core material and at least two coils. The course also delves into the concept of magnetic circuits, explaining how they work in both DC and AC circuits. It further discusses the relationship between the applied voltage and the induced voltage in a coil excited by an AC voltage source. The course concludes with the explanation of the dot convention used to indicate the polarity of the induced voltage in transformers.
