Abstract

In this paper, the power quality for three-phase four-wire non-linear load has been improved using different control
types of shunt active power filter (SAF). The compensated (reference) current can be generated by the control algorithm
and compared with filter injected current through a current controller to generate six pulses for driving IGBT. The source
current should be sinusoidal and in phase with the voltage. Also, the total harmonic distortion (THD) must be less than 5% for
meeting the IEEE standards 519-1992.
