New series Active power filtering system to reduce the harmonic in 3-Phase 3-Wire system

3상 3선식 전력계통의 고조파 저감을 위한 새로운 직렬형 능동 필터 시스템

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
