Design of Novel Dual Input DC–DC Converter for Energy Harvesting System in IoT Sensor Nodes

  • 15 Accesses


A new DC–DC converter capable of working with more than one source for harvesting energy from clean energy sources is proposed. Key features of this proposed converter are single inductor and reduced total number of components. In addition the converter has reduced stresses and power losses. Dual input and output modes, with its operation and steady-state analysis are discussed. Comparative study of the topologies given in literature with a proposed topology for parameters considered like the number of components and voltage gain is presented. Compatibility of the proposed converter is proved with reduced losses using loss distribution analysis of the converter and it is more reliable for energy system in telecom applications, which is validated using reliability analysis, is also highlighted. Finally, to substantiate the working of the non isolated DC–DC converter considered the test results are presented.
