Abstract : Static converters generate harmonic currents and consume reactive power. These new phenomena on the mains generate some perturbations going from malfunction to destruction of the connected sensible equipments. In this paper disturbances generated by static converters are studied. Some solutions based on passive and active filtering are presented. Some passive filter design elements are given. Active filter is then studied. Both structures, current and voltage, are studied and voltage source structure is chosen. Different active filter control principles are presented. The active and reactive instantaneous power theory give good results for harmonic identification. Some numerical simulation are realized. A 100 kVA prototype is realized and tested on an industrial site. The GTO prototype shows good results for harmonic filtering. The voltage active filtering is also presented. The active filter eliminates voltage harmonics on 400 V busbar generated by a MVA SCR bridge connected on 15 kV busbar.
