| Summary: | To facilitate voltage matching between the cell stack and power batteries in fuel-cell-powered vehicles, an implementation of a simple dual-switch boost DC-DC converter topology has been proposed in this paper. Compared with existing boost topologies, the one proposed herein reduces the number of components required and stress induced whilst maintaining a high-gain ratio. The results of experiments performed in this paper reveal that the corresponding to a duty ratio of 0.8, the proposed converter topology demonstrates the realization of a boost ratio of 6, thereby exceeding that the realized by conventional boost converters by nearly 73%. In addition, at an output voltage of 50 V, a maximum operating efficiency of 91% was achieved. These results demonstrate the effectiveness and feasibility of the proposed DC-DC converter topology for use in fuel-cell-powered vehicles.
