Abstract

The work presented in this paper focuses on the design of a half-bridge DC-DC converter for the power electronics interface of energy-storage units for a fuel-cell sport utility vehicle. Several design options are explored; namely: single stage vs. multiple interleaved stages, and continuous vs. discontinuous conduction mode. These design options are weighed against the design goals of minimum cost, high efficiency at low output power levels, and minimum volume and weight to allow for high integration. Special emphasis is given to the impact that the wide input voltage requirements (i.e., from 150 V to 270 V) has on the component stresses.
