Performance Evaluation of Single-Switch Non-Isolated DC-DC Converter Employing TEG using MPPT Control Techniques

Abstract

Inrecentyears, conversion of waste heat into electricity has become an engaging option in both research and industries. Usual waste heat recovering techniques mostly use Thermo Electric Generator (TEG) for the transition of thermal energy into electrical energy. SingleSwitchNon-IsolatedDC-DCconverteriswishedforthethermoelectricpowergener ationsystems. TheproposedConverterhas the advantageofusingonlyoneswitch. Consequently, selectionof theswitchwithlowon-stateresistance reduces theloss during conduction of switchas well as increase the efficiency. Additionally MPPT using the Cuckoo Search (CS) and Incremental Conductance (INC) techniques are used. Proposedconverter is designed withMPPTcontrollerusingMATLAB.
