Comparative Study between Shunt Active Filter and Hybrid Filter
مجلة الجامعة الأسمرية, 2017 This paper presents an comparative study between shunt active filter and shunt hybrid filter based on configuration system and harmonic isolation. The harmonic isolator isbased on Self Tuning Filters (STF) (it can be tuned at any frequency). The study of the active filter control is divided in two parts.
