This study presents a general control strategy for active power filters derived from the current‐shaping principle previously employed in shunt active filters. The generalisation introduced here and denoted as voltage–current shaping control, exploits the symmetry between the possible wave‐shaping solutions, and can be applied to shunt, series, and more complex networks of active filters. Moreover, the proposed generalisation allows the synthesis of specific control schemes with a reduced number of sensors. The relevant properties of the proposed schemes in the application of harmonic mitigation are determined. Further, a discussion of the integration of multiple quasi‐resonant schemes is presented. Using this approach, it is possible to fine‐tune the mitigation of specific components in the harmonic profile from the voltages or currents in the circuit. Experimental results obtained from using a 1 kVA prototype are presented to support the proposed generalisation.
