This paper presents an active filter using synchronous detection method. The equal current synchronous detection method (CSD) is applied to calculate the reactive and harmonic current compensation components for triggering an active power filter in an unbalanced three-phase power system. The simulation and experiment results of active filter operation using the synchronous detection method are effective to eliminate line current harmonics and compensate the reactive current component. The merits of the proposed method are its capability to operate under unbalanced three-phase system by per-phase calculation, to avoid conversion error by force waveform calculation, to balance the unbalanced load and to accomplish well performance by very simple implementation.
