A BIDIRECTIONAL 3-INPUT DC-DC CONVERTER FOR ELECTRICAL VEHICLES

Öz

In this paper, a bidirectional multi-input converter having 3 inputs for electric vehicles is investigated. In order to respond high power need of an electric vehicle during acceleration, the studied converter has the capability of transferring source energies to the output simultaneously by allowing active control of their power levels. It also enables energy transfer between sources to store redundant power or so as to avoid undercharge and overcharge conditions. Moreover, thanks to its bidirectional operation capability, it is also possible to store regenerative braking energy to input sources while keeping energy flow between these sources possible. After giving the deep analysis of the converter operation modes, the converter is simulated through a switching model in order to verify the analysis
