Abstract: Wide use of power electronics circuits resulted in harmonic distortion in power system in large extent. Traditional filters have poor dynamic response while harmonic component changes.  Active power filters are used to improve power quality by injecting reactive and harmonic current, because of its better dynamic response in different load patterns. In this paper a conventional Zero Voltage Switching (ZVS) full-bridge inverter is investigated and reconfigured as Single Phase Shunt Active Power Filter (SAPF). Hysteresis current control scheme is employed because of its simplicity and ease of implementation. The ZVS scheme is incorporated with hysteresis controller followed by reference current generation. The simulation of the proposed SAPF is modelled and evaluated with desirable results in MATLAB/SIMULINK.
