Opis

The high-power grid-connected converters play a vital role in modern power system, realizing the conversion and transmission of electrical energy, and determining its safety, stability and efficiency. This book explores the advanced control strategies of high-power grid-connected converter to satisfy the high-power requirements in practical applications. Special attention is given to grid-connected converter modules in parallel operation to overcome the challenges of non-ideal power grid, power switches faults, and circulating current. Through the advanced control strategies presented in this book, the power capacity of grid-connected converter is flexibly increased with high-reliability and efficiency, thus expanding the application range of high-power converters in modern power system. To facilitate understanding, this book provides step-by-step model derivation and controller design for grid-connected converter. Meanwhile, it also provides the comprehensive simulation and experimental results to offer readers a deep insight into the control process of grid-connected converters. This book serves as a guide for electrical engineers and researchers involved in the development of high-power converters.
