Abstract— This paper presents a shunt active filter based on three-phase three-level (NPC) inverter using two artificial neural network controllers. Shunt active filter is the best solution to eliminate harmonics drawn from nonlinear load especially for low power system, the most inverter used is the two-level voltage source inverter. Multilevel inverters are being investigated and recently used for active filter topologies. Today Three-level inverter becomes a good alternative for most inverter applications, such as machine drives and power factor compensators. The advantages of multilevel inverters is that they can reduce the harmonic content generated by the active filter and can reduce the voltage or current ratings of the semiconductors. Two ANN’s are proposed in this paper, the first one is used to replace the PWM logic controller while the second regulate the dc voltage link of the shunt active filter. The results simulations of global system control and power circuits are obtained using Matlab-Simulink and SimPowerSystem Toolbox.
