Comparative analysis of multi-input DC/DC converter topology for hybrid renewable energy systems

Power electronic DC/DC converters are primarily used in hybrid renewable energy systems having different V-I characteristics. In the past few years, a number of DC/DC topologies have been proposed by the researchers for integration of different renewable sources. Each of these topologies has their advantages and limitations as well as suitability for a particular multi-input sources. The main aim of this paper is to present a comprehensive review of various multiple input DC/DC converters suggested in the recent years. A comparison and discussion of different multi-input DC/DC topologies used for integration of multiple input sources is provided. A comparative analysis based on the parameters such as cost, efficiency, design simplicity, and reliability, is portrayed in order to select the optimum multiple input DC/DC converter for a specific application in renewable energy system.
