A Novel DC-DC Converter Based Integration of Renewable Energy Sources for Residential Micro Grid Applications

A novel converter topology interfacing hybrid distributed energy sources and dc bus is proposed in this paper for integration of renewable energy sources with residential micro grid. This converter has low number of active device compared to the converters usually applied to similar application. Multi-Winding transformer is employed for achieving Low input and output current ripple, high voltage ratio. This paper deals with structure, principle and operation of open loop controller and MATLAB simulation is carried out results verification. Finally practicality of the integration with proposed topology is verified by hardware implementation of hybrid solar PV and Wind Source through AVR-16 microcontroller, also the outputs are compared with the simulation results for confirmation of the design.
