Shunt active power filters are devices connected in parallel with nonlinear and reactive loads which are in charge of compensating these characteristics in order to assure the quality of the distribution network. This work analyzes the dynamics of boost-converter used as an active filter and proposes a control system which guarantees closed-loop performance (power factor close to 1 and current harmonics compensation). Proposed controller is hierarchically decomposed in two control loops, one in charge of shaping the current and the other in charge of assuring the power balance. Differently from other works both control loops are analytically tuned. The work describes both the analytical development and the experimental results showing the good performance of the closedloop system.
