Abstract
In recent years, there has been an increasing interest in DC-DC multi-port power converters for transportation applications. Multi-port converters benefit from fewer components compared to multiple-converter architectures. As a result, higher power density and lower prices are among the main incentives for utilizing multi-port DC-DC converters in transportation sector. Moreover, fuel cell is among the permissible green energy resources that has been broadly considered for transportation applications. This paper proposes a novel multi-port converter for fuel cell-based hybrid streetcar application. Furthermore, an energy management scheme has been proposed for the presented multi-port converter to achieve the suitable modes of operation. Simulation results are provided to demonstrate the effectiveness of the proposed multi-port converter and the presented energy management scheme. Power loss analysis for this converter are provided and efficiencies of 92.7% and 95.1% for two- and single-stage modes are recorded, respectively.
