Abstract

Active Power Filters(APF) have been developed for several years to solve the harmonics disturbance problems on power system networks. This paper studies observer based digital algorithm and PWM technique for three phase current source APF by simulation. Both switching or outside white noises affect seriously at control signal for APF control system. Hence observer algorithm to reduce noises is used. A technique of generation gating patterns for the CSI topologies based on carrier PWM techniques is applied. The requirements imposed on gating signals are satisified by the appropriate combination of single phase switching patterns and short pulse generator.
