The use of electronic equipment in industrial area and households has creat a non-linear loads. This non-linear loads creating the harmonic or pollution for the electricity. This phenomena were decreasing the quality of electric power. This paper show how to design a shunt active power filter to reduce harmonics using an installed parallel multilevel inverters against non linier load. The output of this paper is demonstrate the efficiency or improving between the use of active power filter with a single inverter and the multilevel inverter. The results of this simulation is the value of THD (Total Harmonic Distortion). THD value on a system using an active power filter with Multilevel Inverter showed a significant decrease if compared to the system without the addition of filters or with systems that use the Active Power Filter with a PWM inverter
