Abstract

The performance of the Shunt Active filter depends upon the design of the filter components and control algorithm used to generate the reference current for the switching controller for the power device of the filter. The Shunt Active filter components are the filter inductance, DC link capacitance and power rating of the switching device. The filter inductance depends upon the switching frequency and dc link capacitance. The design of filter requires the basic electrical parameters obtained from Hilbert and wavelet transform. An Iterative method is adopted to design the filter components to minimize the ripple content of filter current and dc bus voltage of the Shunt active filter. The designed filter is switched by the average DG frame control algorithm generates the fundamental reference current and hysteresis controller compares reference current from the supply current. The average DG frame based Shunt active filter is compared with synchronous reference frame controller by developing the system configuration in MATLAB Simulink and the results are verified.
