چکیده
ABSTRACTThis paper presents the simulation of single phase shunt active filter based on PQ theory. Generally PQ theory is used for 3 phases 3 wires or 3 phases 4 wire system but here it is used for single phase system. This paper also concentrates hardly on reduction of THD of load current. Since the system has only single phase signal for both voltage and current, thus the dummy signal with 120 o different angels must be generated for input of the p-q theory. During simulation the six pulses will be generated for switching of IGBT but only two will be used. MATLAB/SIMULINK power system toolbox is used to simulate the proposed system.
