| Popis: | The renewable energy based electrical power generation has the natural characteristics such as unpredictability and intermittency. The challenging task is continuous power supply that is obtained by hybrid system consisting of two or more resources. This research article proposes a transformer-less integrated DC-DC conversion scheme, composed of parallel-connected modified Cuk and conventional Single-Ended-Primary-Inductor Converter (SEPIC) topologies, suitable for application in power generation using renewable sources. The suggested integrated converter topology is operated in such condition that inductor current is continuous, and it employs lower passive component-count and provides a higher voltage conversion ratio than the traditional non-isolated configurations. The power semiconductor devices experience low voltage stress. The steady state performance of the proposed hybrid topology along with the mathematical derivation of voltage gain is explored. A prototype model of the converter is implemented to validate the performance of the hybrid configuration. The output voltage and other performance parameters of the hardware model are compared with that of the simulink setup. |
