Explore this indispensable update to a popular graduate text on electric drive techniques and the latest converters used in industry
The Second Edition of High Performance Control of AC Drives with Matlab®/Simulink delivers an updated and thorough overview of topics central to the understanding of AC motor drive systems. The book includes new material on medium voltage drives, covering state-of-the-art technologies and challenges in the industrial drive system, as well as their components, and control, current source inverter-based drives, PWM techniques for multilevel inverters, and low switching frequency modulation for voltage source inverters.
This book covers three-phase and multiphase (more than three-phase) motor drives including their control and practical problems faced in the field (e.g., adding LC filters in the output of a feeding converter), are considered.
The new edition contains links to Matlab®/Simulink models and PowerPoint slides ideal for teaching and understanding the material contained within the book. Readers will also benefit from the inclusion of: - A thorough introduction to high performance drives, including the challenges and requirements for electric drives and medium voltage industrial applications
- An exploration of mathematical and simulation models of AC machines, including DC motors and squirrel cage induction motors
- A treatment of pulse width modulation of power electronic DC-AC converter, including the classification of PWM schemes for voltage source and current source inverters
- Examinations of harmonic injection PWM and field-oriented control of AC machines
- Voltage source and current source inverter-fed drives and their control
- Modelling and control of multiphase motor drive system
- Supported with a companion website hosting online resources.

Perfect for senior undergraduate, MSc and PhD students in power electronics and electric drives, High Performance Control of AC Drives with Matlab®/Simulink will also earn a place in the libraries of researchers working in the field of AC motor drives and power electronics engineers in industry.
