Elementary Concepts of Power Electronic Drives

Electric drives sit at the meeting point of power converters, motors, and control. Elementary Concepts of Power Electronic Drives builds an introduction to that subject by first examining the components and circuits behind a drive, then following their application through DC and AC motor systems.

K Sundareswaran’s 12-chapter text progresses from converter analysis and motor modeling to drive operation and speed control. The result is a connected view of how electrical power is converted and controlled to operate electric machines.

Start with the circuits behind the drive

The opening chapters introduce drive components and power-electronic circuit analysis, including semiconductor devices and converter circuits. Later coverage spans AC/DC, DC/DC, AC/AC, and DC/AC conversion, helping readers place individual circuit types within the wider drive system.

Follow the development from DC motors to AC drives

Several chapters focus on DC motor models, control, and converter-fed drives. The book then turns to induction motor fundamentals and stator-voltage control before examining inverter circuits and the speed control of induction and synchronous motors. Topics in the contents include four-quadrant operation, line-current harmonics, power-factor improvement, vector control, and permanent-magnet synchronous motor drives.

Connect theory with worked study

Questions and homework problems with hints, along with case studies, support the textbook’s technical discussion. This combination gives students a way to revisit the concepts and engage with their applications alongside the underlying circuit and machine principles.

For electrical-engineering study

This book is suited to readers seeking an introductory, subject-organized treatment of power electronics and electric drives, particularly students studying electrical engineering and related motor-control topics. Its progression from components and converter circuits to complete drive systems offers a clear route into a broad engineering subject.
