In this paper, a Simulink modeling of Active Power Filter was established to reduce the harmonic with high adaptability for kinds of loads. As can be seen in the paper, the effectings of Active Power Filter are based on the Loads’ characteristics, and performance of adaptive with the change of the different types of loads. Fuzzy logic controller was used to proccess the stability of the capacity voltage’s level that was setting up in the Active Filter which was based on the two level three phases inverter.
