Hybrid Power Filters for Harmonic Mitigation in 25 kV AC Railways

Created using ChatSlide

This research presentation delves into the design and implementation of hybrid power filters to address harmonics and improve power quality, particularly in railway systems. It explores the challenges of single filter types, outlines system architecture, and highlights control strategies using p–q theory combined with passive filters. The work examines performance metrics, scalability, and damping in weak-grid scenarios, concluding with insights on experimental validation and scope for future...
