Abstract
A simple SVM-based fuzzy control is presented in the paper. The outputs of the fuzzy controller represent the switching schemes of the voltage-type inverter and lengths of the time intervals composing the switching period. The errors in instantaneous active and reactive powers, which should be generated to compensate high harmonics of a nonlinear load, are the input variables of the fuzzy control of an inverter-based active filter. In order to keep phase currents sinusoidal also in case of unsymmetrical voltage system, a modification of reference average powers is suggested. The control algorithm has been verified by a simulation
