| Abstract |
In recent years the proliferation of non-linear loads has lead to the development of active
filters designed to eliminate current harmonics from the power supply network. This paper
examines the switched-capacitor family of active filters, developed at Brunel University,
highlighting the complexity of the control technique which limits the effectiveness of this
filter configuration. Two different approaches are investigated, with the aim of reducing the
computational requirements associated with the control technique and hence increase the
applicability of the switched-capacitor active filter. A significant simplification is presented
which eases the somewhat laborious, but never the less unavoidable computational
requirements. Genetic Algorithms (GA’s) are also investigated providing an alternative to the
calculus based techniques which historically have dominated optimisation problems. |
