Abstract: Conventional sources are deteriorating the planet; therefore environmental friendly technological solutions are becoming more prominent. This paper presents a new system configuration of the front end rectifier stage for a hybrid wind-photovoltaic energy system. This configuration allows the two sources to supply the load separately or simultaneously together depending on the availability of the energy sources. The proposed design has the Cuk and Sepic converters combined together which eliminate the need of additional input filters to filter out the high frequency harmonics. The fused multiinput rectifier stage also allows Maximum Power Point Tracking (MPPT) to be used to extract maximum power from the wind and sun when it is available. A standard perturb and observe method will be used for PV system and wind energy system. Simulation results were obtained using MATLAB/Simulink.
