Nowadays, in power electronic devices the power quality associated problems are more preoccupied. Different methods of power devices are needed for compensating PQ disturbances. For increasing the PQ one of the power electronic devices used is active power filter (APF). The performance of Shunt APF must be improved by reducing the PQ disturbances. For increasing the behavior of SAPF and PQ compensation a hybrid controller is developed in this paper. The combination of GA and RBFNN method is utilized by deduce the source current for compensation of Shunt APF and decreasing PQ issues. By using SAPF the harmonic disturbances are decreased. The developed hybrid controller method is utilized to make constant DC voltage in the DC link capacitor of the developed MLI. Consequently, developed method uses Harmonic analysis for estimating the THD values. The developed technique is executed in matlab Simulink model. The behavior of developed technique is appraised and differentiated with PI and fuzzy logic controllers
