The design of inverters employing Pulse Width Modulation (PWM) to vary the voltage and amplitude of power electronic inverters has evolved over the past forty years. This is the first comprehensive textbook to view the subject as a whole and to clarify and unify the many diverse approaches taken by researchers.

Klappentext An integrated and comprehensive theory of PWM The selection of the best algorithm for optimum pulse width modulation is an important process that can result in improved converter efficiency, better load (motor) efficiency, and reduced electromagnetic interference.

The book provides a generalized approach to the fundamentals of PWM, looking at: Active switch pulse width determination Active switch pulse placement within a switching period Active switch pulse sequence between phase legs and across switching periods The main benefit of this generalized concept is that once the common threads are identified, the selection of a modulation strategy for any converter topology becomes immediately clear, leaving only secondary factors, such as practical performance, cost, and difficulty of implementation to consider. Additionally, it allows the performance of any particular converter topology and PWM strategy to be quickly and easily identified without complex and time-consuming analysis.

Pulse Width Modulation for Power Converters: Principles and Practice is the first single-volume resource written to help researchers in the field attain a working knowledge of the subject. The authors bring together today?s seemingly diverse approaches into a single integrated and comprehensive theory of modulation.

The book provides a generalized approach to the fundamentals of PWM, looking at:

• Active switch pulse width determination
• Active switch pulse placement within a switching period
• Active switch pulse sequence between phase legs and across switching periods
  The main benefit of this generalized concept is that once the common threads are identified, the selection of a modulation strategy for any converter topology becomes immediately clear, leaving only secondary factors, such as practical performance, cost, and difficulty of implementation to consider. Additionally, it allows the performance of any particular converter topology and PWM strategy to be quickly and easily identified without complex and time-consuming analysis.
