Features: This book is divided into nine chapters. The first chapter introduces the interactive development between power electronic power devices, microcomputer control technology, and variable frequency speed regulation technology. The second chapter introduces the circuit structure and working principles of general variable frequency drives, taking the indirect AC-DC-AC variable frequency drive as a typical example, focusing on voltage control methods and sinusoidal pulse width modulation (SP-WM method). The third chapter introduces the functions and selection methods of variable frequency drives. The fourth chapter covers the use, operation, and maintenance of variable frequency drives. Chapters five to nine respectively introduce application examples of variable frequency drives in elevators, water pumps, fans, machine tools, cranes, electromechanical equipment, and production lines, with a focus on the two major hot topics in the current field of variable frequency speed regulation: the application of variable frequency drives in bus control systems and the application of high-voltage, high-power variable frequency drives.
