This paper proposes an active filter using a series-resonant high-frequency AC-linked DC-AC converter, which compensates the harmonic currents in the utility line generated from the electric and electronic apparatus of the home appliances and discusses the ripple characteristics of the filter. First, an equivalent circuit which describes the macroscopic behavior of this converter is derived. Then, a method for the real-time output current control of the converter to compensate the harmonic currents in the utility line is realized based on the equivalent circuit of converter. The stability of the current feedback loop is analysed by Nyquist locus and Bode diagram to evaluate the ripple characteristics of the active filter. The usefulness of the proposed control algorithm is confirmed by analytical and experimental results.
