Features: This book starts with general speed regulation principles, introducing the principles and structure of frequency converters. It provides a detailed explanation of the three major modes—U/f control, vector control, and direct torque control—to help readers understand the principles of high-performance variable frequency speed regulation. From a common perspective, it explores the design principles of variable frequency speed regulation systems. Finally, it classifies and elaborates on the applications of variable frequency regulation according to load types and application characteristics. For fans and pumps, cranes and hoists, as well as common constant-torque opposing loads, the book categorically introduces energy-saving applications, design key points for potential-type loads, and conventional variable frequency speed regulation principles. For multi-motor synchronous operation, which is prone to errors in practice, it introduces the classification of synchronous types and control methods to facilitate the correct selection of synchronous solutions. The book provides several engineering examples to demonstrate the principles discussed, helping readers better understand and master the content. This book is primarily aimed at electrical engineering technicians, serving as both a fundamental reading material or training textbook for understanding variable frequency speed regulation systems, as well as a reference for engineering design and application.
