    Abstract
    The design for shunt active filter with Multi Level Inverter (MLI) using Fuzzy Logic Controller (FLC) to reduce harmonics. The use of three level inverter shunt active filter has its own advantage in the distortion of low harmonics and reduces the current and voltage of harmonics in the side of the source. THDi in the prior of filter installment is 26,16% and can be reduced to 2,42%. Meanwhile, THDv can be reduced from 0,45% to 0,17%. The fifth order harmonics is the most disturbing harmonics component in which the value of IHDi prior to filter installment, is 21,44% and becomes 1,2% after the installment of active filter.
     
    Desain filter aktif paralel menggunakan inverter tiga tingkat dengan skema fuzzy logic controller (FLC) untuk meredam harmonisa. Penggunaan Multilevel Inverter (MLI) tiga tingkat pada filter aktif shunt mempunyai keuntungan pada distorsi harmonisa yang rendah dan mengurangi stress switching. Dari hasil simulasi diperoleh filter aktif shunt tiga tingkat mampu mereduksi harmonisa arus dan tegangan di sisi sumber, THDi sebelum pemasangan filter adalah sebesar 26,16% dan dapat diturunkan menjadi 2,42%. Sedangkan THDv berhasil di reduksi dari 0,45% menjadi 0,17%. Harmonisa orde ke lima merupakan komponen harmonisa yang paling mengganggu, dimana nilai IHDi sebelum pemasangan filter adalah sebesar 21,44% menjadi 1,2% setelah pemasangan filter aktif.
