This paper presents a new compensation method of series active power filter. The proposed method applied in the three-phase three-wire system can generate harmonic compensation voltage in front of the harmonic source. Futhermore, it is also expended to three-phase four-wire system considering zero-sequence voltage The compensation principle is described in detail. Experimental result show the validity of the proposed method in the three-phase three-wire system.

In this paper, we propose a series active power filter and a simple calculation method acqmring the reference voltage. A series active power filter is suitable to suppress harmonics produced by voltage type harmonic source such as a diode rectifier with filter capacitor on the DC side. The proposed series active power filter system is applied to 3-phase 3-wire power system including the voltage type harmonic source. Experimental results obtained from a laboratory model are shown to verify the viability and effectiveness of the proposed system.

In this paper, a 3phase-3wire series active power filter compensating current harmonics and unbalanced source voltages is presented. The system is composed of series active power filter and shunt passive filters that are tuned 5th and 7th harmonics In this system, series active power filter improves harmonic compensation characteristics of the shunt passive filters and compensates the unbalanced source voltages<br/> In the proposed algorithm, compensation voltage for harmonic reduction is calculated by a performance function, and compensation voltage for the unbalanced source voltage is calculated in based on the synchronous reference frame<br/> Some results obtained from the experimental model using the proposed method are presented to demonstrate and confirm its validity.
