A Double-Port Bidirectional DC-DC Converter for Hybrid Power Supply Systems

Photovoltaics are important kinds of renewableenergies. But the uncertainty about power production of photovoltaics,results in requirement of storage devices. In this papera new double input DC-DC converter is proposed based on athree-switch-leg. Operation principle of the proposed converteris discussed in section II, in section III a modified converter andswitching strategy is presented. In section IV Model of proposedconverter is derived and a sliding mode compensator is designedfor the proposed double input DC- DC converter. Simulationresults is presented in section V for a 2kW hybrid supply systemto validate the proposed converter. Finally, the main features ofthe paper is mentioned in section VI.
