摘要：

Regarding the inherent structure of some nonpolluting resources such as fuel cell (FC) stacks and photovoltaic (PV) panels, the output exhibits a low voltage, which cannot be employed in the common conventional utilizations. Accordingly, an interference dc-dc converter is extremely required. This paper demonstrates the feasibility of using an ultra-high-voltage- gain dc-dc converter in either the FC or the PV applications. While keeping the high voltage gain, the proposed topology illustrates low switches' voltage stress resulted in high efficiency. The continuous and discontinuous conduction operation modes, as well as efficiency analysis, are investigated. The prototype setup of 250 W and 400 V output voltage is implemented. The proposed dc-dc converter merits involving ultra-high-voltage ratio, low switches' voltage stress, and high efficiency are verified via experimental results.
