In this paper a hybrid filter topology for the reduction of the total harmonic distortion in AC sources is introduced. The hybrid filter contains active and passive components. The structure of the digital filter influencing the signals gain and phase will be explained. Furthermore an analytical consideration of optimal filter coefficients is shown. For the validation of the concept a matlab/plecs simulation is presented.
