abstract
This paper presents a three-phase shunt active power filter controlled by the non-linear passivity technique. The dissipative features in which the passivity technique is based on allow the development of a non-linear controller having a good dynamical response, robustness and stability. The control circuit is based on a DSP. Analysis and modeling are presented as well as simulation and experimental results, which verify the satisfactory of the proposed approach.
