“Adaptive Hybrid Active Power Filters” authored by Wang, Wong, and Lam offers a comprehensive exploration of the theory, design, and implementation of adaptive hybrid active power filters (AHAPFs) for harmonic mitigation in power systems. The book begins with an overview of power quality issues and the necessity of active power filters (APFs) for harmonic suppression. It then introduces the concept of hybrid filters, which combine the advantages of both passive and active filters, before delving into the design principles and control strategies of AHAPFs. Through theoretical analysis, simulation studies, and practical case examples, readers gain insights into the performance characteristics, robustness, and adaptability of AHAPFs in mitigating harmonics, reactive power compensation, and load balancing in power distribution systems. The book also discusses advanced topics such as adaptive algorithms, real-time implementation, and integration with renewable energy sources, highlighting the potential of AHAPFs for enhancing power quality and grid stability in modern power systems. Whether you’re a researcher, engineer, or graduate student in the field of power electronics and renewable energy, this book serves as an invaluable resource for understanding the principles and applications of adaptive hybrid active power filters and advancing the state-of-the-art in power quality improvement.
