New control scheme for single-phase active power filters

A new control scheme for a single phase shunt Active Power Filter (APF) is proposed in this paper. The goal is the introduction of a new reference generator along with a repetitive current control scheme. The proposed reference generator uses a filter based on a sinusoidal signal integrator and the instantaneous reactive power theory to compute the APF reference current. The proposed scheme can be easily adapted to work in a distributed generation system, injecting active power into the grid. The whole control algorithm has been implemented on the dSPACE DS1103 development system controlling a single phase APF prototype to demonstrate the feasibility of the proposed solution.
