Three Phase Shunt Active Power Filter Using Simulink
International Journal of Scientific Research in Science, Engineering and Technology, 2021 In AC power grids for harmonic emission reduction and reactive power compensation, activity filters have become very common. The network with non-linear loads such as power converters is equipped with an active power filter for optimizing THD. Shunt type or series type. It also enhances voltage control and unbalance in flicks.
