Abstract: With the concern regarding the state of our deteriorating planet, environmentally friendly solutions are becoming more prominent. This study presents a new system configuration of the front-end rectifier stage consisting of CUK-SEPIC fused converter for a hybrid wind/photovoltaic energy system. The configuration allows the two sources to supply the load separately or simultaneously depending on the availability of the energy sources. With this converter integration, additional input filters are not necessary to filter out high frequency harmonics. The fused multi input 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 microcontroller based control method is used for the Maximum Power Point Tracking (MPPT) of the energy system. For the reduction of tracking time, Fuzzy Logic Control algorithm is implemented with the embedded microcontroller for improved performance. Operational analysis of the proposed system will be discussed in this study. Simulation results are given to highlight the merits of the proposed circuit.
