Design of DC - DC converter for hybrid wind solar energy system

Environment friendly solutions are becoming more prominent than ever, as a result of the concern regarding the state of our deteriorating planet. This project presents a new system configuration of the front-end converter stage for a hybrid wind/photovoltaic energy system. The aim of this project is to implement the converter and inverter for the wind and solar hybrid system. For the hybrid system, extracting as much energy from the wind and solar as possible, and feeding the load with high quality electricity are the two main targets. This strategy makes the hybrid DG system work properly, when a voltage disturbance occurs in distribution the system, and it stays connected to the main grid. Boosting the DC voltage to a sufficient level using the converter, and obtaining pure AC voltage from the inverter, are the keys to realize the above targets. This configuration allows the two sources to supply the load separately or simultaneously, depending on the availability of the energy sources. The inherent nature of this cuk-SEPIC fused converter is that additional input filters are not necessary to filter out high frequency harmonics. This project describes the closed loop mechanism of the cuk and SEPIC converter, and the simulated results are presented.
