Abstract

Traditionally hybrid power generation systems involving same or different renewable sources as input sources AC\ncoupled or DC coupled to the load requires an individual power electronic converter stage for each source. This type of\ntopology needs individual controller for regulating the output voltage. This limitation can be overcome by developing multi\ninput converters which are capable of delivering power to the load individually or simultaneously to the load. Also this\nmethodology would require one controller for managing the power flow effectively and economically. In this paper an\nattempt is made to evaluate the performance parameters viz efficiency , voltage regulation and ripple in the voltage and\ncurrent for different topologies of Dual input DC-DC converters which are synthesized as per definite rules and guidelines\nand compared. Each of the topology is designed for a fixed load and simulated in MATLAB SIMULINK platform to\nevaluate the performance parameters. For getting better efficiency, less voltage ripple, and less current ripple for different\nconverters with constant output voltage by varying duty ratios. From the results comparison SEPIC topology is evident that\nis most suitable topology.
