An Interleaved High Step-Up Dual-Input Single-Output DC-DC Converter for Electric Vehicles

Abstract

Concerning the environmental problems of traditional internal combustion engines, electrical motors have received substantial attention which has led to the introduction of electric vehicles (EV). The integration of several input sources is an inevitable issue to provide EVs with their required energy. According to their higher gain, reliability and efficiency, they are attractive to researchers. In this paper a converter with two battery and ultracapacitor input sources is presented. This converter has a higher gain as compared to that presented in previous topologies. In addition, the output voltage of the converter can be increased by implementing more voltage multiplier cells.
