Abstract

Generally, in diesel-electric locomotives, the energy generated during braking is dissipated in resistors through a dynamic braking mechanism. To exploit this energy, a multi-port system might be employed, using static converters to control the power flow between sources and loads. Due to a lack of space on the traction locomotives, high-power-density DC-DC converters based on multi-state switching cell (MSSC) were chosen to connect sources and loads to a common DC-link. One of the main challenges of this type of converter is the physical design of the multi-interphase transformer (MIPT). Since there is a shortage in literature regarding the MIPT project with more than two windings, this paper aims to present the detailed design of a 1 kW multi-interphase transformer and its validation through theoretical/numerical simulations and experimental results.
