Abstract

This paper presents a new active power filter connected in series with a bank of capacitors having no tuned filters and no resonance problem related with harmonic loads. A capacitor of appropriate small size is determined considering much small power capacity of the converter compared with load power. Through frequency analysis of the system, a dual loop controller is designed for eliminating harmonics of load current and reducing the fundamental voltage component of the converter. Finally, the performance of the presented scheme is confirmed using simulation with 10 kVA 6-pulse load and experimental results with 1 kVA 6-pulse load
