Active Power Filter for Renewable Power Generation Systems Presence of Non-Linear Loads

The performance analysis of four-leg voltage-source inverter using a Fuzzy logic control scheme is presented. The use of a four-leg voltage-source inverter allows the reduction of current harmonic components, as well as unbalanced/Negative sequence currents generated by single-phase nonlinear loads. It compares THD analysis at predictive current control and fuzzy logic control. The compensation performance of the proposed active power filters.
