  • Abstract Extensive use of passive filters has been reported in order to reduce current harmonic distortion levels produced by nonlinear loads. Due to numerous drawbacks associated with passive filters, several active filter topologies have been applied, however the background of this thesis will focus on “Shunt Active Power Filters”.
    The assessment of the performance of the current controllers of the Shunt Active Power Filter (SAPF) is the key point for this thesis. The two most important parts to be concern with respect to the Active Power Filter (APF) is the harmonic detection method and the inner current controller. The harmonic detection method is based on the “P-Q Theory” while the current control techniques studied are: Hysteresis Current Control, Adaptive/Variable Hysteresis Current Control, Predictive Current Control and PI Current Control. Advantages and disadvantages for each current regulator will be highlighted based on same operating conditions.
    Simulation results are obtained for a 9.3 KW diode rectifier load under two load conditions, where after the application of the SAPF it is clear how the source current becomes sinusoidal. MATLAB/SIMULINK software is used, to validate the results.
    After analysis of simulation results, Hysteresis Current Control and Predictive Current Control provides better performance, while Adaptive/Variable Hysteresis Current Control and PI Current Control should be left for other system conditions.
