The Alternating Current Transformer (Classic Reprint)

Transform the way you understand electric power with clear, practical guidance on transformers. This edition explains how a magnetic circuit links primary and secondary coils to transfer power, reduce voltage, and serve near-consumer needs. It blends theory with hands‑on testing and design methods for engineers and curious readers.

The book builds from fundamental principles to real-world applications, showing how induction, regulation, and efficiency fit together. It covers how to measure core loss, copper loss, and how to assess transformer performance under different loads and frequencies. Practical tests, design approaches, and case examples help you connect theory to practice.

• Basic operation: how power moves between coils through the magnetic field.


• Key concepts: magnetomotive force, magnetic reluctance, self-induction, and induction laws.


• How to evaluate regulation, losses, and efficiency in transformers of various sizes.


• Testing and design methods to estimate performance and compare commercial types.

Ideal for readers of engineering texts, students, and professionals seeking a solid grounding in transformer theory and application.
