document: Analysis and operation of hybrid active filter for harmonic elimination This paper presents a hybrid active filter topology and its control to suppress the harmonic currents from entering the power source . The adopted hybrid active filter consists of one active filter and one passive filter connected in series . By controlling the equivalent output voltage of active filter , the harmonic currents generated by the nonlinear load are blocked and flowed into the passive filter . The power rating of the converter is reduced compared with the pure active filters to filter the harmonic currents . The harmonic current detecting approach and DC-link voltage regulation are proposed to obtain equivalent voltage of active filter . The effectiveness of the adopted topology and control scheme has been verified by the computer simulation and experimental results in a scaled-down laboratory prototype
