Abstract

Shunt active power filters are proved a useful elements to correct the distorted currents caused by nonlinear loads in power distribution systems. This work presents an all digital approach, based on the repetitive control technique, for their control and a design is performed for the particular case of single-phase shunt active filters with a full-bridge boost topology. Several experimental results are also presented to show the behavior of the closed loop system.
