Principles of Electric Machines and Power Electronics, 3rd Edition
Year: 2014 Language: english Author: P.C. SEN Genre: Textbook Format: PDF Quality: eBook Pages count: 642 Description: There has been widespread use of electric machines in industries and household appliances. New applications of electric machines have emerged. Novel control strategies, new circuit topologies, and new solid-state devices have contributed to further performance improvements of electric machine systems. This edition is an attempt to update the contents of the book, and to respond to the suggestions of readers and instructors. To these ends the following new material has been incorporated. ▪ Electric machines are mostly used as motors, and in most books the motoring mode of operation is extensively discussed. In recent years there has been phenomenal worldwide industrial growth of wind energy generation. These systems use electrical machines as generators. A chapter (Chapter 11) on wind energy systems has therefore been added for better understanding of the use of electric machines in their generating mode of operation. ▪ In electric motor drive systems, sensors have been used to feed back speed and/or position information. These sensors have several disadvantages, such as less reliability, less robustness, more maintenance requirements, and more cost. Recently drives without sensors have been used in industry. The concept of sensorless drives has been presented in Chapter 6. As well, the coverage on permanent magnet motor drives and brushless dc drives has been updated in Chapter 6. ▪ The coverage of solid-state devices, such as Power MOSFETs, IGBTs, and GCTs, has been updated in Chapter 10. ▪ Power supply in computers, datacenters, servers, and so forth, is an important application of power electronic technology. Introductory coverage of high-power density power supply for such applications is presented in Chapter 10. As well, the popular buck converter configuration for power supply is presented in Chapter 10. ▪ Neutral point clamped (NPC) inverters are gaining popularity for high-power and highvoltage applications. The concept of NPC inverters is presented in Chapter 10. ▪ The book presently has a large number of problems and examples. Additional problems and examples have been added to chapters and sections that appear to have been used by most instructors. In the second edition of my book, very few problems dealt with simple, basic understanding. Therefore, most of the problems that have been added for the third edition are designed to test the basic understanding of the concepts covered in the book.

Description: There has been widespread use of electric machines in industries and household appliances.
New applications of electric machines have emerged. Novel control strategies, new circuit
topologies, and new solid-state devices have contributed to further performance improvements
of electric machine systems. This edition is an attempt to update the contents of the book, and
to respond to the suggestions of readers and instructors. To these ends the following new
material has been incorporated.
▪ Electric machines are mostly used as motors, and in most books the motoring mode of
operation is extensively discussed. In recent years there has been phenomenal worldwide
industrial growth of wind energy generation. These systems use electrical machines as
generators. A chapter (Chapter 11) on wind energy systems has therefore been added for
better understanding of the use of electric machines in their generating mode of operation.
▪ In electric motor drive systems, sensors have been used to feed back speed and/or position
information. These sensors have several disadvantages, such as less reliability, less
robustness, more maintenance requirements, and more cost. Recently drives without
sensors have been used in industry. The concept of sensorless drives has been presented in
Chapter 6. As well, the coverage on permanent magnet motor drives and brushless dc drives

▪ The coverage of solid-state devices, such as Power MOSFETs, IGBTs, and GCTs, has been
