Abstract

Abstract:

When the shunt active power filter (SAPF) compensates the harmonic current,the DC capacitor voltage will have corresponding pulsation,which will have a bad effect on the compensation effect.Based on three-phase three wire system and three-phase four wire system,the causes of capacitor voltage ripple are analyzed theoretically,and a notch filter with specific frequency is put into the voltage loop.The simulation and experiment show that the improved voltage loop can reduce the influence of capacitor voltage ripple.

Key words: shunt active power filter (SAPF), DC side voltage fluctuation analysis, voltage ring, notch filter
