6. Abstract
: This paper presents the design and verification of DC-DC Converter based on Partial Power Processing (PPP) for Hydrogen fuel cell locomotive. Full Power DC-DC Converter (FPC), which is a traditional DC-DC Converter, performs the power transfer by only using the power converter. It causes the bigger size of the power converter, lower power density, and reduced power conversion efficiency. In contrast, input power in Partial Power Converter (PPC) is distributed between power converter and DC-bus. This can reduce the magnitude of the power that is transferred by the power converter, which can lead to a smaller and more efficient system. In this paper, Input-Parallel-Output-Series-setup (IPOS-setup) architectures and Dual Active Bridge (DAB) converter were selected as the PPC architecture and the power converter topology to design the optimal PPC, and it has a maximum power rating of 200kW. To compare PPC and FPC, the size and the efficiency of the system are used. Efficiency of PPC and FPC are drawn through PSIM Thermal module, and down-sized experiment results. This paper proved that PPC can achive up to 1.8% higher efficiency than FPC.
