The design and implementation of proportional-resonant (PR) controller for single-phase shunt active power filters (SAPF) is presented in this paper. The control of SAPF is implemented based on an indirect current control technique which employs the reference compensating current as reference source current. Controller parameters are optimized through the use of Genetic Algorithms (GA). The validation of the proposed control system is done through both simulation and experiment. The prototype of a single-phase SAPF is developed and tested under a real supply voltage which contains harmonics. Experimental results show that SAPF reduces the source current total harmonics distortion (THD) to less than 5% which complies with IEEE Standard 519-2014.
