Lee Hyun-ok et al.: electrical devices

To enable technicians engaged in electrical work to proactively resolve various phenomena encountered in practice, it is crucial to learn and master DC machines, synchronous machines, induction machines, and power converters, which occupy a significant portion of industrial sites. This textbook concisely presents the basic principles and related knowledge of electrical machinery through illustrations to facilitate easy understanding for students at the introductory stage of the electrical field, and is designed to be studied as a one-semester or one-year course at the university level. Furthermore, it is structured as follows to be useful for electrical practitioners and those preparing for certification exams: (1) Chapter 1 covers electromagnetic phenomena necessary for studying electrical machinery and examines the structure, principles, characteristics, and applications of DC machines. (2) Chapter 2 investigates the types, structure, and characteristics of synchronous machines and examines armature winding methods and armature reaction. It also covers the parallel operation conditions of synchronous generators and synchronous condensers. (3) Chapter 3 examines the principles, structure, and characteristics of transformers and teaches methods for representing transformers as equivalent circuits. Additionally, it covers three-phase connection methods for transformers and the conditions for parallel operation. (4) Chapter 4 examines the structure, principles, characteristics, starting and operating methods of single-phase and three-phase induction motors. (5) Chapter 5 briefly examines rectifier circuits for power conversion, AC power control circuits, chopper circuits, inverter circuits, etc.
