A Study on the series Active Power Filter for Harmonic Reduction of 3-Phase 3-Wire System

3상 3선식 시스템의 고조파 저감을 위한 직렬형 능동전력필터에 관한 연구

In this paper we propose a series active power filter and a simple calculation method acquiring 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 result obtained from a laboratory model are shown to verify the viability and effectiveness of the proposed system.
